Will Donovan depart?

With McNabb only having a year left on his contract and the Eagles front office in love with Korn on the Kolb will they get something for him or try to win it all with him for 1 more year. They really like what they saw out of Kolb while he was filling in for Donovan so they may want to promote him to the starter and trade Donovan because there are 2 teams that may need Qbs that can make the playoffs.
The Vikings may be the best place for Donovan so he can be reunited with Brad Childress and have basically the same weapons he has in Philly minus AP fumblemachine (Maclin, Jackson,Celek= Rice, Harvin, Shiancoe). The only thing is Favre may not make up his mind to stay or leave so the Vikes might not be willing to pull the trigger.
The Cardinals might also be a good fit for him. Its his offseason home and he's got a nice set weapons down in the desert. With Kurt Warner probably retiring I don't think they trust Matt Leinart with that team and would rather bring in a veteran like McNabb to stay in control of that weak division.
Other possible destinations:
The 49ers may not want to give Alex Smith the reins and they do have a great D and nice weapons for Donovan. They may just be a QB and healthy corners away from the playoffs.
The Cleveland Browns don't have anything on their team especially a QB but they do have draft picks and that could be something the Eagles are interested in.
The Carolina Panthers may be tired of Jake Delturnover and do they really want to start the season with Matt Moore. They finished the season strong why wouldn't they be able to rekindle that next season with a Probowl QB?
If the Eagles did want to keep Donovan it wouldn't be the end of the world. He's been to 6 Pro Bowls and had one of his best years last season. Its just that he hasn't won a Superbowl in 10 years and its great they're almost always in the playoffs every year but is it ever gonna happen ?Or should they just go in a different direction with Kolb?
