Weren't the new Ghost Recon and Rainbow Six games leaked in that Ubisoft contest a few months ago? Before they were edited out of it.
I'm sure a new Ghost Recon is coming, but I'd prefer to see it shift back to the style of the first game in terms of multiple soldier and squad control, more open environments, no advanced warfighter stuff, multiple objectives and bonus objectives that you can tackle in any order you chose, mission planning and recon, more tactical gameplay, etc. Same goes for the area of conflict. The part of the world that the first Ghost Recon took place in (Eastern Europe, etc) is far more interesting to me. It allows for winter maps, forests, rain, etc. A lot more variety imo.
Agreed with the online single player campaign being co-op as well. If they could somehow manage six player online co-op, basically two squads of three, that would be pretty special. The multiplayer styled co-op is still really fun too, so all of that good stuff would have to stay. The entire online system needs to be fleshed out more, and possibly add in a Halo styled matchmaking and party system on top of the normal way of finding games. I've heard too many stories of poor new players being booted from GRAW and GRAW2 matches just because of their low rank, which hurts the overall community.
