The netcode for Tekken Tag Tournament 2 supports three to five times as much data as Street Fighter IV, according to Katsuhiro Harada.

The Tekken director revealed that he's been discussing the issue of online performance with Street Fighter guru Yoshinori Ono. Capcom and Ono recently released Street Fighter X Tekken, while Harada's Tekken X Street Fighter will presumably be his next release after Tekken Tag Tournament 2.

"It's difficult for a fighting game," said Harada, speaking to at Namco's Gamers Day in Las Vegas.

"I was talking about this with Ono-san. Compared with Street Fighter, the key data that we need to transmit, because of the number of characters and just because of the game's system, is roughly three to five times more than other fighting games. Which makes it very difficult!"

Harada added that the game will use a modified version of the netcode used in Soul Calibur V.

"As you're aware, Soul Calibur V came out recently. I think everyone was pretty surprised and happy with that. We're basically going to be borrowing the system. Our technologists have really done a good job on doing more data compression techniques, they've helped out with that.

"I think people will be pleasantly surprised."

Tekken Tag Tournament 2 will be released September 2012 on PS3 and Xbox 360.
