Are you sure it's the SAGA Cloud City Chewbacca? It looks more like the ROTS Chewbacca to me...
The OTC set really sucks... this is just straight up horse-sh!t.
As for retailers... sorry if I missed it, but who is going to have these? Looks like TRU exlusives or something.
For $20, I can live with it. Except for the OTC one... they need to really make some serious changes with that set, and here's how I would do it -
Vader - make it the VOTC version w/ removable helmet
Luke - make it the SAGA Jabba's Palace version w/ a black right hand
Chewbacca - VOTC w/ the ROTS head
Han - VOTC w/ Endor colored pants and vest
Stormtrooper - VOTC version
This would be a hot set if they just did it right!
