The rumors were true! The young Calrissian is indeed coming to Star Wars: Rebels, and StarWars.com's Tim Veekhoven posted this first look at the young gambler/smuggler/scoundrel. Lookin' good, Lando.
That he does! Supposedly Lando will appear in the episode titled "Idiot's Array," which will air on January 19th, but there's no word whether he'll be piloting the Millennium Falcon, if he already lost it to Han, or maybe it's even before the Falcon entered his life. At any rate, he will be voiced by Billy Dee Williams, the one man in the galaxy who can accurately capture Lando's smoothness.
