Rumor has it that Lego will be releasing a UCS Slave 1 in 2014. (Eurobricks, BrickFan, etc).
I for one am literally thrilled if this is so.
Slave 1 is my favorite of the iconic ships in Star Wars, and it hosts the two best bounty hunters ever. I'm sure I'll acquire over twenty of these if its really going to be released. Speculation says around May 4th promotion again.
if a new Slave 1 is released (regardless of the included minifigs) for the film, there's a chance things can play out similar to 10240 (UCS X-wing) and The Force Awakens X-Wing sets. Thus some people can legitimately assume UCS Slave 1 isn't going to stay around into 2017 unless Lego "thinks" it's a big-time seller.
note: many experienced AFOLs think 10240 was suppose to disappear earlier but stayed around because certain folks kept buying them.
