Best believe if the Marvel license was the newer one and it was Spidey, Wolverine or comic Hulk and not Batman right now there'd be 2000 Spidey, Wolverine and Hulk EXs as well. And I'd be all over that ish! Just the same if DC was the older license, their ES would be like the Marvel peices are now. Joker would be an old grail by now and everyone would love the Batman Comiquette more than the PF
But let's not forget Marvel isn't dead, we've just had the biggest of the biggest already. But there's still B-list characters left like Magneto, Daredevil, Phoenix, etc. Even fairly big characters like Loki, Blade and Ghost Rider (movie exposure made them all). All are more popular than Ivy (although being a sexy female was in her favor) so I'd like to see their ES, but it depends on sculpt and EX as well. The 3 DC sculpts so far have been better than many of the newer Marvel sculpts. Yeah Skaar was good, but he's not A, B or even C list. And even a great sculpt like B/C-List Hawkeye got messed up because there were no switch out parts. They haven't had that great character/sculpt/EX combo on the Marvel stuff lately like they have with DC.
