We've got some new hub exploration footage and I'm seeing the same minor problem with the demo where you hit A and it immediately jumps to the end of the message without any sounds. Recall in Banjo where you can press and hold A to simply speed it up a bit, and the voices will even match the speed.
I wouldn't really mind if the default text speed wasn't as slow as it was. (Even if it wasn't, its fun to manipulate the speeds anyway.) Has anyone spotted these sorts of options in the menus at all?
As a side-note, the footage looks excellent.
