Isn't this how the industry work?? 3rd parties have a job to create an install base too, otherwise they leave themselves nobody to sell their new games to. Nobody is going to stick around on PS3 and 360 forever, technology has moved on and so will the gamers.

I think it's weird, but because I thought gaming development was expensive enough with the 7th generation consoles. Bioshock Infinite sold a good number, but even then they forced Irrational to shut down. Didn't Assassin's Creed III take $100 million to develop? I don't know, maybe the x86 architecture will make development time shorter and easier, but those higher polygon counts and apparently every franchise going open-world (Mirror's Edge 2, Metal Gear Solid V, LEGO) are still going to cost a lot of dough

ps2 got games for quite a while

Actually I don't think you're right. Theres alot of games coming also for ''previous gen''.

Xbox and GCN didn't, though. PS2 just had too big of an install base too ignore.

till 2007 for cube and 2008 for xbox
and the install base of the 360 and ps3 is even bigger 

Those 07/08 games were just yearly Sports ports, not AAA games or anything.

And PS4/Xbone are doing better out of the gate than PS3/360 did, which encourages devs to make the transition more quickly.

Sadly that should be the trend for every generation. But at least we have luck, one/ps4 are doing amazingly, so they have confidence releasing their games exclusively on next-gen.

ps2 didn't get many cross gen games.. because it was way too weak..

the darkness didn't come out on ps2 like thief did on ps3 and ps4.. HD dev cost is so high that they have to release the game on several platforms.. since low settings on pc = last gen for new games.. and high settings on pc = current gen they might as well release both versions

poor wiiu.
