Heavy Rain, Uncharted, and Demon's Souls.
Heavy Rain and Uncharted are no brainers, and I do believe film lisences have been picked up for both already anyway. Demon's Souls tho, I could see that being a dark and gritty film with amazing CG, and with such a silent world (well silence talking wise, I mean it's all demon's and human stragglers outside of the nexus) hopefully it would keep the cheezy Hollywood popcorn flick catch phrases at bay a bit.
I'd say inFAMOUS as well, but almost certain a film version of that is already in the works as well, so not so much a wish list as a wait since it is coming out.
