Almost bought the special edition (I am a sucker for VGM CDs in particular), then caught myself; I didn't care much for the demo, so why buy the SE? The poster art is nice enough for what it is, though it wouldn't go up in my house. Where do you guys land on this stuff? Models and posters and trinkets? Personally I try and keep the gaming paraphernalia down to a minimum, or else things start getting out of hand... I allow myself the odd coffee mug, got a Spelunky mug, Pac-man, a Dopefish (old id Software in-joke) and a Roland TB-303 retro synth mug (not strictly game related but very influential among certain popular game composers, cough-YuzoKoshiro-cough). Got lots and lots of VGM CDs/vinyl, though (and even a few tapes), so I guess I break my own rules.
I know we've all been saying it, or hinting at it, but I do really hope they go back to classic Umihara Kawase design after this. ~60 tightly polished levels, multiple exits, randomly spawning enemies hand-placed enemies, a few bosses that can be quickly dispatched or otherwise skipped if you're competent enough. It's a simple enough formula, they've got the engine for it, and even their 3D art is looking accomplished by now. I didn't really want to play any more of this game after the demo, though, which is just sad.
