I can totally see these coming back again someday, as ten-dollar sets with some changes.
Han could have his chest remolded to allow for a removable vest. They could remake his gunbelt to be removable, and slap a removable stormtrooper belt in the package too.
Chewie could have "poppable" head hairstyle changes, and a removable bandolier (if not already.

) and gas mask.
Luke could come with a ton of accessories--all the old T-16s, tools, rifles, floppy hats, maybe even a poncho. Then give us the blastshield training helmet and a new lightsaber with snap-on training remote. Throw all that in and they would have a "new" figure I would pay ten dollars for (whereas I'm not gonna buy him in the VOTC pack).
Vader could be remade with a plastic cape, and removable headgear. Throw in some other accessory and he'd be "new" and worth it too.
I don't think we're seeing the last of "most" of the parts of the VOTC. Definitely never in Vintage packages. I can see why they'd be reluctant to make them 5-dollar figures someday, though. After the "special" Fett became a pack-in twice, I don't think collectors (at least, not openers)would bite on the special 10-dollar figures anymore.
