Wii u hardware sales have stalled currently. Nintendo are going for a big christmas promotion, likely a price cut with a bundled game and if that sells a lot of wii u consoles then the major publishers will start developing again but the result of that will be late 2014 I guess when they hit retail apart from more simplistic games with short development periods.
PS4 and Xbox one are being treated differently as they are expected to sell higher hardware numbers and be bought by users with higher disposable incomes (older gamers) who buy the more major titles. Publishers are expecting these consoles to sell better than wii u.
Of course we don't know how ps4 and xbox one will sell. At the beginning you often have a huge number sold like wii u but then after the early adopters its difficult to keep sales rolling. Neither console offers backwards compatibility so the library of games will be low for sometime and they are even more expensive consoles. However I think its fair to say there is a buzz about ps4 currently and most are expecting that to do very well.
I think Nintendo will push again for the casual crowd to buy wii u. Their current marketing has been weak. They are even stopping the video channel on wii which they could have used to solely promote wii u. I don't get their decisions recently.
I'm not a Nintendo loyalist though I just love games. If NIntendo are forced into lowering prices to increase market share or wii u titles are quickly discounted because of low sales then I'll be paying less for games which is good. A 3 way console war is great for consumers, it means plenty of discounts. Although that won't help me with the xbone games because I'm not interested in that console at all. I'm hoping it will offer some competition to the ps4 though so Sony keeps its prices low.
We don't want to see an outright winner that is for sure. Sorry to take the thread off track a bit.
Even if EA goes back to developing games for wii u they will likely be ports from the 360/PS3 versions of games running at the same level of performance approximately. Do we even need those games on wii u. Unless such games make heavy use of the gamepad to enhance gameplay I will be more interested in the ps4 version of such games. Also if they are using an engine not currently written for wii u someone has to adapt it to the wii u first. That won't be easy if the engine is expecting higher cpu performance and routines have to be written to maximise the amount of work done by the gpu.
The poing is will there be consumer demand for weak wii u versions of games that perform at the same level as ps3/360? I personally don't think much demand will ever be there even if the wii u sells a lot of consoles. I think the main wii u audience will be the casual crowd and people that love NIntendo games. It's a younger, more family friendly audience really.
I think realistically at best is we see EA casual games for wii u late in 2014 if the wii u market share recovers and I don't think this is that important to wii u success.
