I think a lot of people were somewhat surprised at Tekken 7 not being announced for Switch, so I thought there would be some interest in Harada's answer.

Don't expect that to happen. Harada and producer Michael Murray, who translated the interview, have not even been able to get their hands on a Switch as of yet.
"Officially, we can't really comment on that because our company has strict policy about which titles we talk about for Switch," Harada explained. "But personally, we've been so busy with trying to master up Tekken for the current platforms that we haven't really had enough time to study the hardware. We couldn't even buy it--it was sold out every time we went to look for it."
