It's not like a fanboy thing, where i blow out my birthday candles wishing for the falcon in ep III, in case i gave that impression...I take it as it comes with star wars (and roll my eyes at some of it)...
So far they've squeezed in almost every single major character from the original trilogy, except han and lando....r2, 3po (clumsily linked to anakin), luke, leia, tarkin, mon mothma, boba fett, jabba, the lars etc etc (and wait for them to announce ackbar).....
they will never get han and lando in because there's no way to tie 2 infants into the script convincingly (although i wouldn't put it past george to try).....but if you say lando's 37 in ep V, that makes him about 17 in ep III, and if that's too young for him to own the falcon then it would be the previous owner who would appear in ep III....simple logic...
If it happens i hope it's not obscene and innapropriate, but it could well be....and waynerobsonuk's right about the used ship trading, check luke sell his landspeeder in ep IV.....
