Rare for killing themselves
Lionhead for killing Fable
Codemasters for killing the rally genre

I wouldn't say Square Enix, they saved me a lot of time this gen!

One that disappoints... rare.

No, not the old discussion they are dead and stuff.
I loved kinect sports (seriously, now I'm a bit tired but my first weeks with kinect were amazing on so many levels)

But every single regular to good dev can make Kinect Sports, it's not a game for rare.
It's like using Rockstar main team to do Carnival Games, no matter how good it is, it's just not right.

So I was disappointed that's the path Rare went

Be patient, GTA 5 I'm sure will be excellent.

First thing that came to mind was Square Enix, when I read the title. I tried to think of others, but I just can't seem to find anyone that has failed so hard.

Nintendo.

Il have to go with Nintendo ( As publishers, not devs) due to the fact that we had to fight for almost 2 years to get xenoblade and 1 year for Last Story.

But the devs that im the most disapointed in are probably Capcom.

I'm disappointed in Nintendo also.

Not making Wii in HD was a major down for me, really really bad on a 50" and up TV. But in the end portables took my attention anyway, so I didn't cared much for the wii or other consoles.

Square Enix...by far number 1 for me then its Capcom.

I guess Team ICO as well has been a big disappointment, I don't care how amazing the game will be you can't take 7 years to make it!

1) Square Enix: Treatment of PS3 fans, FF13, Versus, etc. Yuck
2) Crapcom: Awful
3) Team Ico: Last guardian?
4) Polyphonic Digital
