I'm disappointed in Square Enix, Final Fantasy 13 was one of the worst games I ever played, and they still haven't come out with Kingdom Hearts and Final Fantasy Versus. 

or they could have just not put all that unnecasary crap in their in the first place, but i do see your point, doesnt change the fact that they GROSSLY overestimated the PS brand if they thought it would fly off the shelves for that price

Didn't piss me off, but I was very dissapointed with FF XIII. After 15hours I couldn't get myself to play it anymore. The story was just plain bad IMHO.

Capcom, while im happy they brought fighters back to to forefront and i still play SF4 and 3 did they have to really go back to their old lets sell multiple versions of the same game thing again??
SE the publishing arm is probably better than its ever been, but goddamn what happened to the devs. FF13 was straight meh, we still havent seen Versus, no word on Type0 localization. KH3, but that doesnt bother me too much because BBS and 3d are of the highest quality. IT seems like the only people that know what the hell they are doing are the guys working on the portables.

Websites with coundown timers that exist to hype up a game reveal. Most recent disappointment: TWEWY Solo Remix countdown website.

Playstation All-Stars got delayed...

No seriously, i can't think of much else that bothered me.

It got delayed one month. Originally October 20ish to November 20 (US)/November 21 (EU). Not a big delay but it kicked me in the ovaries. 

@ bolded - indeed, Studio Liverpool should never be closed down...

also, yes... pretty much these points... also, all the XBox 360 Halos sucked compared to two in my eyes

(btw. Sony Fanboy, Halo, Gears of War and Crackdown are the only XBox 360 exclusives I bothered to play, imho Crackdown being the only one worth playing)

also, Nintendo, for not giving me moar Zelda on mah Wii, but well, I got 2 games... don't remember one gen having moar than two...

I'm disapointed that gtav has'nt come out yet,that is all.

Uhg, damn Capcom..
