Ono does realize that piracy of the PC version gave the game a wider spread, but Capcom could not continue with the title being "free" in certain territories. A PC release wasn't ruled out, but it would hinge on better anti-piracy protection.
A PC port would be incredibly easy to create at this point as the arcade version in development runs on hardware that is essentially a Windows XP machine. This also means that an illegal version of the game could find its way online. Earlier this year, pirates were able to rip BlazBlue: Continuum Shift, which runs on the same arcade hardware, and release it as a fully functioning PC program.
