I really need to, but I can't bring myself to start Ratchet & Clank A4O. I bought it as a sheep, I didn't like the demo/beta at all.

Edit: I also can't bring myself to finish the platinum for Uncharted 3 (I have it for the first 2)

Don't feel too bad, Vanquish has the best gameplay of any action game this generation, you'll have a blast. 

Oh I know, I played a few hours of it already. It's a shame such a great game never got any hype......

Probably Pandora's Tower.

Skyward Sword after I get the platinum on LA Noire. I only got the PS3 in October, and then went on holiday - to further slacken the pace for LA Noire, I got Skyrim when it came out, and that has sucked sooooo many hours out of my life!!! Still gotta complete Super Mario Land 3D.

Since I have a big backlog I use a tool to control it and also to choose my next game for me. Yesterday I finished Rayman Origins (22 hours with all electoons and all teeth) and my next game will be Castlevania Lords of Shadows, and it suits me as I am also playing Castlevania Judgement at the same time.

After that, it depends if Xenoblade Chronicles arrives on time THAT will be my next one, looks great and I have been waiting for it for more than a year, if not I will use the tool to choose my next one.

Having finally gotten 100% in Red Dead Redemption I can now move onto Psi Ops: The Mindgate Conspiracy.

Finished Mass Effect 3 last week (what a shitty ending), I´m now replaying Castlevania Lords of Shadow on a higher difficulty, and after that I´m buying The Witcher 2, everything I´ve seen and read about the game makes me think I´ll enjoy it a lot.

Castlevania: Bloodlines on the SEGA Genesis.... And, maybe some other games on my genesis wish-list.

Next game I start will either be Atelier Meruru or Pandora's Tower, just depends on how the timing works out.
