Well The future of gaming looks like this:
(I am talking about consoles and PC's)
AAA Games FPS, TPS, ACTION ADVENTURE, MMORPG, SPORTS GAMES FIFA MADDEN. games with bloated budgets and masses of hype that if they fail to sell will take down devs, but if they make a profit hope you like seeing them run into the ground...
Nintendo Games (yes is a bit catch all but you get my drift)
Indie Games
Downloadable games from XBLA, PSN, Steam, WiiWare, lower risk meaning lower budget, you may get the Odd SHMUP or Port of a fighting game.
Then there is
shovel ware just flooding the market with cheap crap.
Games that are going the way of point and click (not aas relevant as they used to be)
SHMUPS,FIGHTING,Racing, Experimental games that cannot turn a profit (brutal legend etc)
and Platformers (I dont think they will be as relevant as they once were, except for Nintendo Games)
Handhelds will suffer sales hits due to Android/App store low prices and shovelware apps, see GTA CTW for example hopefully Nintendo will be the exception, but again it is usally Nintendo Developed games that seem to sell better than thrid party games
Well the games industry was fun while it lasted
