Got a chance to play it at P1 this weekend, and I like it, but it seems really chaotic. I think I had 4 of the main multiballs running at once at one point? I'm also not sure what's up with qualifying chapters and collecting items (at least I think that's what you're doing). It's a game I definitely need more time with, so I'm looking forward to playing it at Nick's next week, especially since I want to see whether the LE is worth it. P1 has a standard out, and it seems fine, but the deal breaker might be the RGB GI. If that's well integrated, then it might be LE or bust.
Of course, if I want to buy one, that's $14k that I don't have right now. Also might hold off to see what hardware changes they come up with in the interim, since there's always something...
