I think I'll let the 7965 MF slide away without buying one. Chatter here is correct: there will be a new one out soon, putting a lid on this one's value.
Anecdotally, my 6-year-old lives and breathes Lego Star Wars. He wants it all. He has a DS, and he wants an SSD (not likely), an AT-AT, Mos Eisley, Star Destroyer, an MTT, a Spider Droid, a Starhopper, a Ghost, a Phantom... and on and on. You know what he doesn't want? A 7965 MF... couldn't care less... just of no interest to him... he already has several Lukes, Leias, Hans, and Vaders... so what does he need this boring MF for? And the whole "chrysanthemum" opening top never appealed to me. A new, bigger, more interesting MF is needed... something more than just a place to play space checkers.
Also... someone earlier commented that the DS has to go because Lego doesn't want to raise the old US$400 price ... and it's worth more than that today? I don't know.... just doing a little apples to oranges math: The 10188 DS has 3803 pcs and 24 minifigs (and some of those - like the mouse droid - are barely what I'd call minifigs). The new 5004243 Classic Collection has 3839 pcs and 24 real minifigs for US$390. Of course there's only one Death Star, but the new sets are about the same price as the old.
