just a quick idea i thought of, there are so many games i still need to buy before this gen is out on PS3 so i thought il list them and peopld can do the same for PS3/360/Wii. 

Then others could give there opinion on what they should add/remove from this list! so here goes:

Pandora's Tower
Fatal Frame 2

PS3:
Yakuza (any of them)
3D Dot Game Heroes

360:

I received my copy of The Last Story yesterday, but I haven't opened it yet.

I'm also taking 'before next gen' to mean before a platform will be succeeded by a new console by the same manufacturer, so Wii games before WiiU launches, PS3 games before PS4. I'm assuming WiiU will launch late this year and PS4 will release late next year. In that case, I'm hoping to get:

Tales of Symphonia 2 (Wii)
Tales of Graces f (PS3)
Ninokuni (PS3)
The Last Guardian (PS3)
Project Zero/Fatal Frame 2 remake (Wii)
FF VS XIII (PS3)

most of my future purchases are looking like they will be on the 3DS which is 8th gen.

Wii:
Xenoblade Chronicles
The Last Story
Pandora's Tower
Fatal Frame 2

PS3;
Dead Space 2
Demon's Soul
Dark Souls (if I like demons)
Valkyria Chronicles
Dragon's Crown

But if the Wii U comes at a higher than expected price I will buy a few others in PS3 that will also come to the Wii U, like Darksiders 2, Batman Arkham City among others.

I'm more looking forward to next gen. games but I guess there are a few.
