i don't think VF5FS could cause such a big pain in losses. at least SEGA should do something for their VF fans after all these years of waiting.
Given that it be a port of a Lindberg game, I don't think they'll make a loss at all, but it just sell so poor, it would be a bit pointless (but it would be nice) Both tekken and VF needs a serious reboot for the Home (arcade is a different matter)
regarding Border Break i kind of agree but i don't think the single player will be properly done, cause i don't think sega will give the developers the time they need , personally i think the game can stand on it's own without it
in this day and age you'll need a decent single and multi player modes and I think the game is strong enough to a disc based release
