I think Toyota stays as it is. Evans last year struggled due to the diffs, which have to be the same for all drivers but in the meantime I read that they did some changes and as we can see he's winning rallies again (even if sometimes benefitting from circumstances).

As for MSport I think it's too early to speculate, as my feeling is they themselves don't know what they can do yet. Regarding Loeb, it's not a question of convincing him, I think it's simply a question of paying him to drive the car, somehow I doubt anything he does he does for free. Solberg I don't see it happening because of things already mentioned, probably another year in Rally2. Also seing the issues the various customers had with the Puma if I was in the position with money in hand I might rather go for the spare Toyota as Bertelli did...
