I think PS4 will get past Wii U, but it really doesn't matter to anyone. I believe Sony has already divided the world this way:
PS4 for the West
PSV for Japan
I don't expect many Japan-centric 1st party games on PS4. I think PS4 is gonna get pretty much only big 1st party Western games and big 3rd party Japanese games. These 3rd party games will most probably be multiplats with XO (if MS manages to save it, that is - otherwise the Japanese might decide to not even bother), but since nobody in Japan has ever heard of something like an Xbox, they will count as PS4 exclusives in Japan.
On the other hand, Sony's 1st party studios in Japan will be pumping Vita exclusives and we already know that all Western Vita studios are working on PS4 games. 3rd parties are starting to flock to Vita in Japan as well and this seems to be the kicker. Vita gives the Japanese developers the lowest development costs out of the three and an install base larger than Wii U and PS4 combined. This is the main focus of Sony in Japan.
On the other hand, Sony has recently started this whole movement of localising all Japanese games and this may bring back the good times of Japanese games in the West. If that happened - all devs would immediately flock to PS4 and it would become a powerhouse in Japan.
Wii U is a GCN 2 - I called it months before the release!
My Vita to-buy list: The Walking Dead, Persona 4 Golden, Need for Speed: Most Wanted, TearAway, Ys: Memories of Celceta, Muramasa: The Demon Blade, History: Legends of War, FIFA 13, Final Fantasy HD X, X-2, Worms Revolution Extreme, The Amazing Spiderman, Batman: Arkham Origins Blackgate - too many no-gaemz :/
My consoles: PS2 Slim, PS3 Slim 320 GB, PSV 32 GB, Wii, DSi.
