Count me in as one of the ones who will gladly get this on the day it comes out, despite the fact I own all three original games on the NES and already own the game for SNES. I think the extras packed in justify the purchase. Besides that, I can play it on my Wii without having to dig for the cords that go to my SNES.
I have admittedly been rabidly following this since it was announced in Japan. I put my $5 down at Gamestop this evening. Can't wait until Dec. 12th...
