The biggest issue going around BGE with the advent of Sesame Street, is if/when the sale of the parks occur, how the rights to Sesame Street will be transferred, if at all.
Paramount KD had similar issues during the Cedar Fair transition (Italian Job Stunt Coaster - Now Backlot Stunt Coaster) and BEC is no more exempt from that possibility. It will be just one of those things that will most likely have to be carefully negotiated within the terms of the sale and come to an agreement with Sesame Street for name rights transfer between companies.
Hopefully the "new" company doesn't have current name rights to "South Park".. Wouldn't that be lovely :-)
