Well, to be fair, the PS2 was a bit too hard to get up to par, with Arika even having given up on the faithful port of Ketsui, a PGM game. (Cave themselves weren't as pedantic with that console and the early SH3 ports to it, and we all know how it turned out.)
X360, on the other hand, has more performance headroom than is realistically needed, and you can have every thinkable option there (save for true 240p output, which just won't happen anymore). I got a Japanese X360 as a shmup console, and I have used it extensively as a shmup console, but that decision was made already after five or six genuinely good shmups had been announced for it, offsetting the cost of purchase and import, as well as the console itself getting a significant discount. Cave?not to mention other devs?would have to release at least a couple games absolutely worthy of a next-gen console investment?I expect upwards of 500$ for the console itself, the cabling, a controller that doesn't suck too much, and importing all of that. That's even disregarding that for some reason I really dislike the thought of getting a damn number-crunching powerhouse to run software designed for Dreamcast-level hardware and still have it slow down and occasionally stutter because it's more cinematic and?OH MY GOD THE BLITTER IS GOING TO CHOKE CALL THE AMBULANCE, with the ports having to stay true to the originals.
I may change my mind if Cave's new console of choice is actually damn good, durable and comfortable to use, but so far one good game with mid-2000 era visuals is just not convincing enough.
