Are Chevy Chase and Beverly D'Angelo making vacation plans?

Reports are telling us that Chevy Chase and Beverly D'Angelo are in talks to reprise their roles of Clark and Ellen Griswold in the upcoming reboot of the Vacation franchise. They would be joining Ed Helms and Christina Applegate if other reports are to be believed.
As the original film did in 1983 the reboot will follow the misadventures of the Griswold family as they head to Walley World.
