Buy Samsung Galaxy S3 deals?

[katavellock]

I’ve been checking out some fantastic things about the Samsung Galaxy S3 at: Samsung Galaxy contracts however I simply can’t afford it at the mo so my friend said I may want to buy the Galaxy S2 as an alternative as it's still performing pretty well.
I am thinking that it'll be the same as the iPhone 4, when the 4S was let loose. The 4 was lowered in its selling price so in theory the Samsung Galaxy S2 might go down in price once the Galaxy S3 is circulated.
So Im wanting to know how much the Samsung Galaxy S2 costs right after the Samsung S3 is put out and do you know when its going to be on the shelves?
