If Ferrari hire Raikkonen, then I don't see this ending well for anyone if Alonso's there too.
For Ferrari, it could be a major disaster and lose a big sponsor, Raikkonen will probably get beaten by Alonso since the teams been around Alonso and know what he needs in a car.
Then there's the fact there could be a bust up between the three. We've already seen Alonso making snide remarks to the team for a quite a few races now.
Add to that, I don't think the move seems right for Raikkonen. With Ferrari reportedlty having the worst engine out of the three an KERS, then also windtunnel problems for the last 3 years, I just don't see them being competitive in the next few years, add to that, he's going to a team that paid him not to drive, and then he's up against one of the best currently on the grid today.
