If they are "rebooting" the line and starting over symbolically with the Luke, Leia, R2 and Chewie - I hope (for sanity's sake), when they do this, it means that they're going to handle the line a bit more like it was handled during the vintage days.
There was only ONE Tatooine Luke from ANH - sure he got re-released under the ESB and ROTJ banners, but there was never a second, third, fourth, etc... sculpt of the figure.
I would be happy if they use this line to put stakes in the ground and say "This is the ultimate Tatooine Luke and we'll never make another version of Luke in this outfit." If done with the right amount of accessories (long rifle, floppy hat, tan poncho, swappable belts (black vs. Stormtrooper) , binoculars, imperial blaster and lightsaber (lit and unlit)) and a high-level of articulation (at least 15 points) -- then I'd be okay with that.
If you think about it this would help the line survive the longest. Constantly re-issue the exact same figure in the exact same packaging and your profit margin goes up.
I could see them making eight Luke figures and that's it - ultimate versions of Luke from Tatooine, Luke in Stormtrooper Disguise, Luke in Flight Suit/Gear, Luke in ANH Celebration Outfit, Luke on Hoth, Luke on Dagobah, Luke in Bespin Fatigues, Luke in ROTJ (with plenty of accessories to cover Jabbas Palace, Endor AND the final duel).
If they took some of the same principles they have already started to put into some figures and incorporate it into EVERY figure, this could easily be done.
Take for example Luke in Hoth Gear - all you need there is some interchangeable hands, two heads (pre and post Wampa attack), well articulated legs, ankles, ball-jointed shoulders and jointed elbows and you're all set.
Luke in Flight Suit could come with enough interchangeable pieces so that it would apply to either X-Wing OR Snowspeeder
Jedi Luke could have interchangeable hands, black vest, camo poncho, rebel helmet and lit/unlit lightsabers.
For other characters there would be only the need for one or two versions - Darth Vader, C-3PO, R2-D2 and Chewie all come to mind.
The other plus is that they might be thinking of applying VOTC type detail to PT characters. Who wouldn't LOVE to have a SA Darth Maul or Jango Fett?
