If PC ends up being the only feasible way for the game to make it out of arcades then I'll take it, but I'd much prefer a PS3 port with a physical release. It would likely sell much better in Japan, where PC gaming is very niche, anyway. French-Bread must also be aware of how relentlessly Melty has been pirated on PC outside of Japan.
Also, GGPO isn't an instantaneous, magic solution to netcode problems. Like anything else, its rollback system needs to be implemented well, taking into account the unique mechanics of each game. Look at SFIII:3S Online for an example of a poor implementation of GGPO. Additionally, Sega's netcode for VF5:FS remains the best I've ever used, and it's not GGPO.
