Sorry but you are retarded.
Have to edit to make it relevant:
Yes, I believe "THE GTA V GAME IS GONNA ROCK!" I believe this because Rockstar consistently releases top quality games, all the way from III - LA Noire. It is evident that they put a lot of effort into their games, so I really doubt they would keep it a secret because it's "GONNA SUCK". Also, they wouldn't release a trailer if the game was no where near completed. I imagine they'd have been working on it since 2008. In addition, the trailer seems to be 100% gameplay footage which indicates they've got something done.
But so you can understand here it is, nice and simple.
"THE GTA V GAME IS GONNA ROCK".
