WiiU doesn't even get the PS360 ports right, or barely, with horrible framerate, like in Batman or COD recently.

So obviously there s no way, as expected that WiiU will get ports of the true next gen games that will come when crossgen cease. By the end of 2014, the WiiU will be totally on her own te get games.

Wii/GC's TEV unit may have been an alternative to programmable shaders, but it worked very differently, making it difficult to translate effects over from programable to TEV. It was also less convenient and took a lot more work to get results out of; normal mapping, for instance, could be done on Wii, but you had to do it in a really roundabout way that bewildered devs used to programmable shaders, to the point where only about FOUR games in the Wii's entire library used normal mapping at all. (Conduit 1 & 2, Metroid Other M, Dewy's Adventure)

Wii U doesn't have this gap with PS4/Xbone; all three use programmable shaders. Wii U may not have all the same features, but it is confirmed to have DX10/11 equivalent functionality, so it won't be in a whole different ballpark like the Wii was.

The Playstation 4 reserves 3.5 Gigabytes for the OS. Thus: 8 - 3.5 = 4.5.
512Mb of that is "Flexible" thus putting it on par with the one.

That may be so, but it could still do most things Direct X 9 capable hardware could do, some things it can't, but that works both ways.
So from a technical perspective, it wasn't a hindrance from a technical perspective.

Besides, the TEV was used in 2 generations of consoles for many many many years, developers got the hang of it eventually.

Thankfully, Nintendo made the WiiU a little easier to deal with, even if the hardware is anemic.

What could the TEV unit do that DX9 level programmable shaders could not?

Does make me laugh if you go to Metacritic front page and click on Games, the 2 best games out are for the 2 "Dead" Platforms

I'm pretty sure the power of everything scales similarly to previous generations. And it's all in relative context to Moore's Law.

It was the hardware which lead to the loss of the 3rd parties which lead to the lack of interest with the help of barely advertising. So its the cube over again. They will weather it like the cube.

Lack of dedication to establish franchises is what killed third party support. The sales thing is just an excuse. 

yer but that could be going back a generation. Don't forget 3rd parties only judge on current performances. So sales is the excuse.

Besides EA games, the Wii U is actually getting pretty decent versions of major multiplatform games. The other versions of the games have just as many frame rate issues as the Wii U versions. It's more about developer talent than hardware limitations. The difference between multiplatform graphics this gen will be far less obvious than other generation. For example:

PS4/XB1 - 1080p 60fps Vs. Wii U - 720p 30fps
N64/SAT - 480i 30fps Vs. PS1 - 240p 20fps.
