Games getting announced too early by Sony?

[Peh]

Well, I wouldn't say only Sony, I've noticed that from Microsoft, too. Too early announcements for games, some of them end up really bad or are getting canceled in the process and some being delivered with what they promised. But I guess this is being done to keep the hype up and show that their console have the software to look for.
For the most time, Nintendo announces the games which will be releases within a year. There are some exceptions of course like some Zelda games.
