You seriously thought it was going straight to console?
Well...yeah. Capcom Fighting Jam went straight to console, and Marvel versus Capcom 2 was released for arcade the same day it came to Dreamcast. Powerstone was actually released for Dreamcast the day before the arcade version (not that anyone would notice).
Capcom officially left the arcade biz years ago, and has only come back with some rare exceptions. The only arcade release from them I can think of since then was Street Fighter Zero 3 Upper.
Giving SFIV's bastard origins (and bastard appearance, and we can only assume bastard gameplay) I just assumed it would be straight to console. At this point you might as well just say that its a Japanese arcade release since finding it in the states will be harder than finding a Turbo Duo at your local Game Stop location.
I live near what used to be (and still is, I suppose) one of the best arcades in the US, and I wonder if even they will get it. Their newest machines are all either pinball or imported from Japan, and even those aren't exactly spanking new. I have no idea what's even being released for arcades anymore.
Beatmania IIDX 15th Style DJ Troopers just came out in Japan...Time Crisis 4 was like... a while ago...even the stuff being released in Japan is like those stupid card game things.
