I don't think anyone with an S3 on a 2 year contract will have any reason to drop contract or use an upgrade for the S4. I think manufacturers understand now, as well as many consumers, that annual phone releases are for those finishing their 2 year contracts opposed to those in the middle of the 2 year contract. This will be a jump for S2 owners, but not S3. Allows for a steady progression and predictable sales & revenue. That said, I'm sure others still will need the latest piece of shiny metal and I say more power to them lol.
