Jordo I think the issue may be that a 7 speed doesn't cost much more, but Toyota doesn't have a 7 speed and they'd need to build a new one. So they just took an off the shelf 6 speed, made it shift a bit faster and rougher, and threw it in without changing the gear ratios. They could've used one of the newer 8 speed units but those are probably more expensive and overkill for a wimpy 200hp motor.
The story sounds about the same for the manual too really, they didn't bother revising gear ratios either.
I guess if it helps bring the cost down, okay
