This rumor seems to have been going on for years. According to recent interviews with the filmmaker, Robert Zemeckis has announced that a sequel(?) to Who Framed Roger Rabbit (1988) is being planned and he will make use of motion capture technology plus 3D like the last films he has directed.http://movieblips.dailyradar.com/story/roger-rabbit-2-is-being-written/
I dunno, it could be a good thing and I would like to see Roger again, but in CG and 3D?
