Romance RPG - No not for me, thanks, but women gamers are a growing audience and there could be a market for this style of game if done well and thoughfully.
Social based MMO - This could take many forms, but a key componant would be to create and maintain a large social network of friends/allies which you can then get to preform certain tasks for you, or trade/sell or obtain info etc. Could involve setting spys into other groups to gain into and give them misinfo. This also creates a sense of who-do-you-trust-with-what play. Could be similar to My Sims or FFCC:My Life as a King (or whatever it's called) except you need to entice REAL people to come/work with you.
Vertual simulators - Part Virtual Boy, Part Wiimote - Totally encompassing simulation of action, FPS or Sim gameplay. BE a Jedi Knight! Large open space required.
