Is Metal Gear Solid 4 sole reason for Sony PS3 sales success?

Many people are talking about the sales of the Sony PS3 and that sales have boosted because of the major success of the exclusive Playstaion 3 game Metal Gear Solid 4: Guns of the Patriots.

The sales of the console boosted through the month of June, this goes to prove that Sony PS3 exclusives are a must for future sales of the gaming console.

If there are exclusive games many gamers will buy the PS3 console just for these games, like upon the release of MGS4 Sony released a sales bundle which was just for that game, this followed the man himself, oh yes Snake on his epic adventure.
