jayderyu: actually, your statement about the PC market not being robust for fighting games has to be tempered by the fact that there aren't so many fighting games available for PCs.
For the longest time, the main "viable" one was MUGEN which wasn't really legal ^^
Growing up I often regretted that not more fighting games were available on PCs, and with the recent arrival of SF4 (yeah I still consider it as recent), DiveKick, SkullGirls, the platform is developing for fighting games. (I let aside blaze blue "voluntary" I haven't played/checked it out and from what I understand it's a more ********** fighting game, pretty much the kind I couldn't get into as it would require too much involvement before being able to truly appreciate it/be good at).
I'm not sure C2, ATM, is the best platform to develop one though (the previous network issues mentioned will require some strong technical work, I'm also not sure you can plug an arcade stick atm (at least mine doesn't seem to work last time I checked a few months ago) which will be kind of a barrier for FGC).
Spriter is definitely a tool I would use to make such a game though, allowing to gain time on developing/implementing the characters, allowing to "move away" from rectangle hitbox from games like SF for example and provide something new. Nevertheless, like C2 and HTML5, Spriter is also a work in progress. The good news is that the development of the game could go along the one of C2/HTML5/Spriter and all could evolve nicely together.
To get back to the game itself, there is still a big lack of informations to see if it is a viable project, yet I'm looking forward the next posts to see how it goes.
