Honestly, I'm not too excited about the X-Wing Luke. We need a new Snowspeeder version of him much more badly... and as for making custom X-Wing pilots, I'll just keep using the Dutch Vander body, which is just a $5.00 figure and is damn near perfect.
Greedo - Guess it makes sense, though I'd rather see Tarkin or a Death Star Trooper get the royal treatment.
Tusken Raider - Already have about 25 or so mixes of the POTJ/SAGA versions, but a few more might be nice, especially if it has cloth goods.
Han Solo - Makes sense... but I still think they should just add this into a Han Solo Evolutions set
Scout Trooper - Please, please do this the right way...
I think they are missing the boat in not offering in some fashion Han and Luke Stormtroopers in the VOTC style...
