Speaking to OXM, SFIV producer Yoshinori Ono’s conceded that online play in the game is going to present extreme difficulties.
“Obviously, lag will be a huge problem for online play,” he said. “We’re working on it. Compared to other games such as Virtua Fighter and Soul Calibur, they’ve got replay functions and so forth. It’s quite difficult for 3D Street Fighter at the moment.”
Ono wasn’t fibbing. The team really is trying to sort it out.
“In order to prevent the lag we’re thinking about trying to balance it up at user interface level and input timing by using joystick or something like that,” he added. “We still haven’t got a complete plan as yet. We’re still working on it. That’s all we can say at the moment.”
There’s a full interview through that link. No timing on console versions as yet.
