But the sales of the late ports on WiiU were good enough for the sequels to come to the platform in pretty much all cases.  

If the Xbox One version is selling on par and the PS4 version selling 3x the best selling WiiU late ports, then we can assume that the sequels will be coming to these platforms too and that will be the real test of how well PS4One have held up.

You also raised late ports as a reason for the WiiU versions not selling as well.  Take a look at the PS4's current software sales totals and examine the late ports.  The best example is FIFA 14 which was over 2 months later than the PS360 versions yet is on 1.4m at the moment.

Even Injustice, which is a late port also available on PS360; WiiU; Vita; iOS etc. looks like it's going to beat the best selling WiiU late ports, which are from far more popular franchises.

(And speaking of franchise popularity, we were comparing Tomb Raider with Batman before.  Batman on PS360 sold over 9m while Tomb Raider on PS360 sold around 3.5m.  You could take that as "more people have played Batman already!" but I would take it as "Batman is a more popular franchise with more sales potential").

I get where you're coming from with this but I feel like you're trying to argue points that aren't really there to make WiiU's failures seem better.

No, I could really care less about Wii U's failures.  I was simply making a (only half-serious) point that late ports do poorly.  Tomb Raider did relatively poorly whether you're comparing it to other titles on 4One, or to its previous release on PS360.  I don't actually think 3rd parties should or will drop support for XBOne.  But 3rd parties have given very poor support for titles on Wii U in terms of release dates, content, price and promotion, and they are getting the corresponding sales results.  If every 3rd party game on 4One was like TR:Late Port Eddition, Wii U would look much less weak in comparission.  But that isn't the case.

Also, FIFA is a poor example to bring up because a) it's FIFA, b)it was only delayed a couple months and c) it was a bundled title.

1) If "it's FIFA" was enough, then why is the WiiU verison on 140k LT sales?

2) Even worse.  A late port like Batman on WiiU at least has some enhanced features making it different from the previous releases.  FIFA was merely the same game as on PS360 but a couple of months later (at which point you'd expect everyone who wanted it to have bought it).

3) No, it wasn't.  It was bundled as a download code on XB1, but I was directing you towards the PS4 version.  The official PS4 bundles have been using Knack and Killzone.  If there are unofficial retailer bundles that's fine, but those stand true for WiiU games as well.

Also this sentence:

"Tomb Raider did relatively poorly whether you're comparing it to other titles on 4One, or to its previous release on PS360."

If we're using relatives, why don't we say it did relatively well when you're comparing it to WiiU late ports?

I can see you're not going to change your stance on this one though, so we're just going to go around in circles without a conclusion if we carry on with this.

Publishers dont support Wii U not because of later ports, they saw that even bundled launch exclusive games like zombiU dont sell very well on Wii U ( to compare, Dead Rising 3 sold 1M in 2 month when zombiU sold 630k in 1 year and 3 month ) , they saw that even port sell very poorly on Wii U ( assassin's creed 3 or Black flag or COD sales compared to the equivalent on PS4/One )

All of your receipts are based on assumptions that Wii U users aren't Nintendo fans who have two or three consoles from the previous gen and that most TRDE buyers didn't bought the PCS360 versions which contrary to your opinion isn't really popular tbh when we're dealing with late ports.

The general belief on late ports is it won't sell that much on next gen consoles related to your previous gen console of your choice which already has the same game on its library.

With that on mind, Arkham City selling less on Wii U is an anomaly.

It's going in circles because it's off the main point I made.  Even if TR does double or tripple or more than a title such as Batman:AC (which launched on a userbase 1/10th of what TR is launching to), the the title is still a relative bomb when compared to it's earlier release or other releases on 4One that are not late ports.  At .1 of the sales of top software on 4One and .03 of the sales of the original release, it is - mathmatically speaking - much, much more of a realative bomb compared to other releases and at 2-4X Batman:AC much, much closer to Wii U late ports, relatively speaking.  It isn't really up for debate where its sales lie.  4X and 30X are not relatively close.  It is far more accurate to say that it performed similar to Wii U late ports than to say it performed much better than them.

Who has this "general belief" and what data is it base on?

X1 can still win because of kinect and the casual mass market. But a price drop will be needed soon. For hardcore gamers however, the X1 GPU is just too weak in order to compete with PS4.

This needs to stop.  If being a launch game is such a detriment to the sales of a title then you'd never see anything but first party software on a console at launch, ever.  Userbase doesn't matter as much when there's launch hype and people are picking up titles to play on their new machine. 

If it's really bothering you that much then why don't we use an improved late port on WiiU instead, like Deus Ex which opened to a 3k first week and 36k LTD?  But that would obviously make matters a lot worse, so...

Then yeah, we're just talking about different things.  

To use the PS4 as an example (because it's what I've been going with so far), Tomb Raider has sold 114,978 in Europe + USA (with more regions to come).  The top selling PS4 game (both at launch and LT, as far as I can tell) is CoD Ghosts.  FW in Europe + USA was 625,470.  

114,978 / 625,470 * 100 = 18.38%.  

If we compare it to Arkham City WiiU (since we've been using it all along), which had a FW in Europe + USA of 35,577:

35,577 / 114,978 * 100 = 30.94%.  Not exactly close, but far closer than the picture you were trying to paint.

So .18 compared to .31.  Sure, if you want to be absolutely correct you can say it was more of a bomb compared to other PS4 launch titles than Arkham City was a bomb compared to Tomb Raider.  But again, Tomb Raider was a vast improvement (both in terms of sales and revenue) over the sales of Arkham City; sales which were good enough to ensure the next instalment came to WiiU.  And at the end of the day, isn't "getting the userbase familiar with the franchise in preparation for the next instalment" what these late ports are all about?

I think in all cases it was about milking exsisting assets for some extra cash.  Especially in TR's case.  With Batman and several of the other Wii U shovel ports, I think they were making sure they didn't miss out on the chance to grab some money on the next Wii craze and get a presence early - which of course didn't happen.  These late ports are easy extra sales that they (obviously) didn't get on the first release, and they can often charge a premium for the version on the new system.

And yes, the userbase does matter.  Wii U was in around a million homes at the launch of Batman.  PS4 and XBOne are in 3-5X that with Tomb Raider.  So having 2-3X the sales is natural, especailly with userbases so small.

Especially when looking at the One version of TR, it's really in the same ballpark as the late port's on Wii U in terms of sales and attach rates.
