I think now that time has passed, you could tell by Michael Schumacher's behaviour over the years, he knew that Kimi wasn't quite geling with the team, and always promoting Massa, his protege to the world, and I think he kinda enjoyed seeing it, as I think he wasn't too overjoyed with ferrari signing Kiimi so early, Michael said, he was behind the cecision to sign Kimi, as he recommended him to ferrari president, and Michael was behind the Alonso to ferrari move as well, but whether or not the signing of these drivers came at the right time for Michael, I don't know, sure they wanted a top driver, but it was michael's ferrari, maybe Michael thinked he was due more power then he already had, you had some respect there with Massa and Michael, but Kimi was strictly a driving coming into a team that was broken a decade ago, Michael was apart of the team building and success, he helped make ferrari a team drivers want to go too, and I think Luca may regret signing Kimi so early, and this Alonso signing is trying to recapture some sort of Schumacher team leadership thing, maybe it would be a exceptional move, but when you got Schumacher himself coming back into a different team, and Schumi's protege Massa at Ferrari keeping his legacy flowing as Massa is a connection to the master, then Schumacher is really perhaps denting Ferrari's outlook in 2010.
Ross Brawn and Michael Schumacher, they you think should be at Ferrari, I didn't think Brawn would leave ferrari, and further yet, not Schumacher, this is now big tough challenge for everyone potentially, Alonso in a new team that Massa knows, it's not ideal, and ferrari having Ross Brawn and Schumi to contend with if he signs, it could just be ferrari's biggest hurdle, their former strenghs against them, friends turned rivals, not ideal, how much knowlege they have.
I'm sure Ferrari would prefer Schumacher back, but I think maybe after all, Schumacher is done with Ferrari, just needs a completely new environment, otherwise I'm sure Kimi leaving ferrari, it would mean Schumacher back and Alonso waiting until 2011 or 2012.
Alonso I'm not sure fits well with Ferrari yet, I think him and Flavio and Renault worked well, I'm not sure if Massa is good for Alonso, it's like keeping Schumi's Brazilian Spiritual brother protege around to keep him under pressure, that's what it feels like.

Anyway, it all depends on Alonso's approach and where he's at in life, he could do very well.
