I'm going to throw out mine:

Demon Souls
I am 100% with the concept behind this game, but I'm still not sold on the gameplay. I'm rather picky about such things, and there is no demo on PSN so I have been putting it off.

Resonance of Fate
Looks interesting, but I'm a little gun-shy by the fact I have been don't think I have played a JRPG made in the last decade that hasn't disappointed me.

Valkyria Chronicles II
I found the actual combat of the first one to be brilliant and quite enjoyable. However, I found the scouting and moving forces across huge maps aspect of be frustrating. I like the maps that are tight without a large dependence of scouting, or a huge map where I have to wait forever for my slower units to keep up. Is it exactly like the first one, or has it been tweaked a bit?

Final Fantasy Four Heroes of Light
Is this kind of like FF3?
