Check out this excerpt of an interview with Katsuhiro Harada by Spong at GamesCom 2012. I'm interested in how Tekken fans would feel about all future Tekken games having tag functions.
"Will there be a Tekken Tag Tournament 3, or will we see all those Tag features merged into Tekken 7? Series producer Katsuhiro Harada has suggested that the franchise could see a bit of a rejig to ensure that the spinoff series becomes unspun.
"It’s hard to say at this point, but it could be the case," he told SPOnG at Gamescom. "ForTekken Tag Tournament 2, even though the name says Tag, you can play one-on-one [as you can in the traditional Tekken games] and you can play two-on-one," he continued, "so it is already kind of merged into this one game.
"It could be the case that this setup will be the standard [for our games] in the future. It will be hard to say until the game comes out."
