Whether it be a game remade, Sega re-entering the console market, or a cross-over game of your choice... I have a few, here's a couple in order of which would make my gaming dreams come true...
3) Final Fantasy VIII full remake - not a typo, VIII was one of my favorites, but has a lot of room for improvement (such as the crappy draw system)
2) Suikoden 2 being released on PSN - Hope one day this comes true
1) Star Wars Knights of the Old Republic 1 & 2 released on PS Vita - God I loved those games
EDIT (honourable mentions):
Tekken (my favorite series since PSone) reduce the over reliance on juggles and bounds - Tekken Revolution has done this! :D
A new Star Wars Battlefront - God I miss it and its happening! :D
Full 3D Street Fighter - With Tekken X Street Fighter still planned, this should happen! :D
ONE I FORGOT IN ORIGINAL LIST
Finally, some SOLID info and news surrounding the release of The LAST GUARDIAN
The best way to find out if you can trust somebody is to trust them.
