Well that's true. Ultimately it will come down to sales though. If the game sells a respectable amount on the Wii U then Ubisoft might decide to release some of the DLC for the game. But if it doesn't, then it would be unprofitable for Ubisoft to do that and so I think  that's a fair reason for not releasing DLC on the Wii U. Wii U owners need to just be happy they are even getting the game. 

So, it took Ubisoft half a year to add in a gamepad map? Are they mentally deficient? Are they the sped class of game development?

The game is going to bomb on the Wii U. Not trying to be pessimistic

This would have probably made a difference six months ago. Nobody cares now.

Nop, it took them 3 weeks, the additional 6 months they use them to catch up as the development of this version of the game was stopped from January till june of this year, is actually a small miracle that they decided not to cancel it all together, but I am happy with that decision, I rather have a late game that no game at all.

they tried some stuff. it didnt work. IT is what it is

Possibly similar to how the pick-pocketing was in Assassin's Creed and hacking a car on GTA, both on the DS with the latter a weak use of the stylus though.

They keep on trying to whitewash (found this word by online translator and i guess it is not too wrong) what they did with WatchDogs and to the WiiU-owners.
As an compensation they should sell it for max 39€/$ at launch, so that it is about the same prize as XBone/PS4 Version but of course they will NOT do it.
I still think it would have been better if they canceled the WiiU-Version and i really really hope Nintendo was not stupid paying Ubisoft for still releasing it on WiiU.
Ubisoft ... if you are really really lucky, WatchDogs on WiiU will do 350k LTD, but most likely even less.

nice try Ubisoft ...

Ubisoft believes that people still care about this game? The cocaine and alcohol must be good over there.

Bolded 1: Why? having a game in the console is always better than not having it, why so many people lack the empathy to see that many people just can't afford a second console? the console NEEDS all the variety it can get, is very hard to offer a product that lacks many options, and to be honest the line-up for november on the Wii U is very bad, this game adds an option, cancelling it would be a very bad idea.

Bolded 2: 350k LTD would be GREAT!!!, way above expectations even from Ubisoft, I would really be surprised if they are looking for anything beyond 150k, which should be enough to cover portings costs and nothing else, that is why they are abandoning the console right now, their games don't make enough money on it, which as a bussiness makes sense.

Wii U owners just don't want this kind of games, the sales of previous titles proved them that is was not worth investing on it, beyond the ocassional Just Dance titles and some other child properties, half the consumers are too unforgiving... when a game has framerate problems it automatically becomes "a piece of garbage, that I will not buy" and the other half of the audience just does not know/care for this games.
