To hold, I like the B-Wing and Jabba's Palace. Neither will be redone anytime soon. B-Wing has the UCS designation, while JP has some phenomenal minifigures, and a very isolated place among the SW lineup with no similarly sized remakes. It also has Jabba and some great minifigs, and Rancor Pit and Desert Skiff to partner with a couple years after EOL. Quick back of the napkin on a potential sale in 1-2 years:
Purchase price
JP - $81
RP - $41
DS - $18
Total - $140
Future Bundled Sale Price - $300
I think that's a realistic possibility for a future sale price for these, and frankly there's a good chance these go for more. Time will tell whether it hits this price or not, but we're still talking about a nice payoff at $300.
