@Mummelmann: If you put it as "globally" (=all major markets) available, then you're correct. The "global" availability, btw., was the reason why 360 was the fastest selling console of all time before the Wii.

Sony made the PS3 release based on where they thought they'd had the worst competition.

1.) The PS360 situation and Wii U situation are very different. If there was any developer who didn't release a game on the PS360 after they launched, it was more than likely because they didn't release any games at all. For the most part, big games released on time on the PS3 and 360. The same cannot be said for the Wii U. There are a lot of notable games not announced for the Wii U that are announced for the PS360 - this didn't happen with the PS3 & 360. 

2.) I'm not sure what you're trying to say here. Are you saying 3rd party games wouldn't appeal to Wii U owners?

3.) Multiplats will help. Without them, that leaves Nintendo as the sole source to provide games with the Wii U, and we all saw how that turned out for the Wii. Yes, exclusives 3rd party games are important, but I seriously doubt we'll be seeing many notable 3rd party exclusives next generation. If this generation has showed us anything, it's that 3rd party loyalty is gone. Aside from the rare title like Bayonetta (which isn't that big to begin with) , I don't we'll see the Wii U or any console getting many 3rd party exclusives. 

Also, even if Nintendo's strategy didn't involve multiplats, that doesn't mean it's a good strategy. Plenty of people value multiplats for their console; some even say multiplats are the best games available. And if the Wii U lacks multiplats, then those people have the right to criticise the Wii U for it. Just because Nintendo doesn't think they need multiplats, that doesn't mean plenty of gamers don't want multiplats. Plenty of people don't want another console with Nintendo releasing 90% of all the good games.

4.) I don't doubt that the Wii U will have more 3rd party support than the Wii. But I do expect it to be severely lacking in comparison to Sony's and Microsoft's outings.

You can understand 'Doom' threads for the PS3 at launch (there were a few months when the GBA outsold it lol) and the Vita because those sales have been pretty poor, I couldn't say why people are jumping on the Wii is d00000med bandwagon, partly fanboyism and partly people (for some reason known only to themselves, including industry 'experts') expecting the Wii U to be the ridiculous sales phenomenon that the Wii was I guess.

The worldwide sales figures are reasonably impressive so far, the only territory that isn't doing so well is Europe but it's hardly been a flop over here either.

What people seem to be forgetting is that Nintendo and third parties have only announced launch window games for this year. We don't know what the third party support in comparison to the PS3 and 360 is going to be like. A great deal of these games that are due for release this year have been in development for years on the other two platforms before the Wii U was even announced. What we'll end up with we'll have to wait and see, we'll know more after GDC in March, via Nintendo Directs and during E3 this year.

As for when Sonyt and Microsoft release their current gen efforts it's going to be easier for developers to port between the Wii U, PS4 and 720 than it currently is porting between the Wii U, PS3 and 360 thanks to Nintendo's forward thinking with their choice of GPU and architecture, and with the Wii U likely to have a 10-15m installed userbase by the time they're released publishers aren't going to be leaving that sort of money on the table.

It´s always the same, they never learn. Remember 3DS ??

That is perhaps the best double entendre I've seen on this forum. I don't know whether it's a Freudian slip or intentional, but it's very impressive either way. Well done. I applaud you, good sir.

Anyhow, on topic, Nintendo fans mocked Sony when Vita sales were ridiculously bad so now Sony fans are capitalizing on the fact that Wii U sales are slightly bad and trying to mock Nintendo. Nothing more to it.

the wiiU was doomed even before it came up... just let them vent all their frustrations and move on...

Believe it or not there are still people in denial about the 3DS. I made a claim on another forum elsewhere when discussing the 'threat' of mobile games to handheld and home console gaming that the 3DS has had ridiculously good sales, particularly since Animal Crossing and Paper Mario have been released, and he/she denied it. The mind really does boggle :Oo

You definitely seem confused about what I am saying so I'll try my best to clarify. I would buy the multiplats. Other wii u owners would buy the multiplats. But the people who bring up this argument about third party support, what about them? What if gta v, lightning returns, dark souls ii and metal gear zeroes were all confirmed for wii u? Note, none have been ruled out so it is possible. Would they go out and buy it? Or would people turn the cheek and say "oh they have third party support now but they can't keep it". For multiplats its simple. Things just slide into place if you play your cards right. Thats the reason the multiplats argument holds no value. Wii u could have every big multiplat of this year and I'd wager it still wouldn't 'convince' people. Thats what I'm trying to say there. Its the people calling wii u on it and complaining in the first place that are at fault. They complain but fail to do anything when it gets addressed to them. Aliens and injustice are on wii u. They are better examples. People could go buy them but how many of them that complained in the first place will? That is the real problem behind this myth of third parties on wii u. Its not that they can't sell. Its that the large majority of people who own multiple systems don't take the option as they are given it whereas I do. It would be great for me if wii u had those multiplats but I bet the majority would just be shrugging it off anyway. I'd wager they go with the latter scenario and say "they won't keep it". They'd be saying "why should I go out and buy a wii u when I can get those on my ps3/360?" But for multiplats, if nintendo use this well, yes things will just slide into place and multiplats will get there by default.

For the others you never know. I suspect sony's struggles with ps3 and vita will have hurt their reputation. Then you have to note that sony could very well be too late to make an impact on the market since it seems highly unlikely they are releasing this year. There are tonnes of ways this could go. I don't think it will be as simple as the others coming out and wii u being abandonned. The others face some serious problems by using power as a selling point. People think power will be enough but its more likely that it will come down to the games. One thing nintendo can play to their advantage is the japanese market. Microsoft isn't accepted there and nintendo are. Trust me, this time next year for japan at least, you'll understand precisely why getting monster hunter and dragon quest helped them. I expect a lot of japanese games (and these are the games I care about in general anyway) to get on there by default. Even long after the others come out. But for multiplat support, things just slide in place later. I would love to play dark souls ii on wii u. Hopefully I get the chance but for the average 360 and ps3 user they would probably shrug it off anyway. This year wii u is likely to get some late ports and day and date releases. After that we'll have to see. The consumers will decide.
