Should Kyle stay or go?

It has been debated as to whether Kyle Busch and Dale Jr should go ahead and switch rides before the end of the season. That's if Kyle Busch signs with DEI. After watching the post race interviews, I don't think Kyle will make it the whole year, he seems to be a very bitter person right know. I like Kyle and think he is very talented and (and still hate that he is leaving HMS) one of the best drivers on the track, but it may be better for him and Hendrick if they part ways now.
