That's a really good comparison.

My take: PS3 > Wii U > Xbone

Xbox One should win this easily...

Xbox One, Titanfall and Halo.

Why are guys talking about Halo 5? Is it confirmed for 2014?

Anyway, Xbone is the safe bet here, but i can see some scenarios where PS3/WiiU could win this.

XB1 for sure... but imagine if it didn't, then XB1 would be Wii U2....... and U2 is a great band.

Difficult to predict:

1) a price cut down to very popular price, plus the existing library and some new games could boost PS3
2) growing game library and possibly a price cut could boost XBOne
3) new big Ninty games, showing a lot more focus and commitment to it and maybe a price cut could boost Wii U

If all of the three received their boosting factors, then the fight would become very interesting, and what's better, the whole industry would benefit from that, with a general boost that could avoid a decline from 7th to 8th gen.
The same applies to PSV too.
PS4 and 3DS both deserve their respective leaderships, and to sell even more than now, but let's wish the whole market better a lot, even PS4 and 3DS can't do it alone.
