I don't think many people oppose the two, the Wii U is not in a good position right now... and obviously the Vita is in a worse position...
Current consoles "positions"
PS4: Great, plenty of content being released all the time, plenty of system selling all the time... get good bumps when big titles get their release (even multi-plat form titles like Watch_dog)
Wii U: Not so great, may be discontinued early or a follow up console may come sooner than expected if sales don't pick up next holiday with the possible release of a new Zelda game
XB1: Selling OK, not nearly enough (MS stated they expected to ship 1 Billion of those... not sure to who yet) I think it will have a similar success to the OG xbox/Game Cube...even the Titanfall hype train did not give this machine that much of a sales bump, so my guess is the buzz around it is pretty weak.
PS3/xb360: sales are falling, 360's sales are falling even more sharply, I think MS will abandon the 360 before Sony abandon the PS3.
3DS: Are Nintendo satisfied, do they see a future in hand-held gaming? it's selling at about half the rate of the 2DS... Still it has a solid library
Vita: Sony said they were disapointed in the performance of the device, despite it being arguably, the "better" hand-held it has a good library as well, but tittle interest from many gamers... I expect it to be discontinued before the end of 2015
