Mid 80's. From what I played I would give it a 90+ but there will be a bit of backlash due to lack of voice chat. It might be lower because there are some reviewers that seriously HATE any form of motion control at all and will dock points due to the default using motion controls. If they take the time, about 3 or 4 seconds to switch off motion controls and not bitch about it, it should rate pretty high. Some might be like me and find that in this situation, the motion controls are the best scheme I have ever used in a shooter (Keyboard and mouse included) and I want ALL shooters to use a similar control scheme, it should rate quite high. It's still a simplistic game, point and shoot and the idea of covering/controlling the most area with ink is novel so most should be able to pick up and play fairly easily, which should lend itself to high ratings. Lack of weapons at release might lend itself to some critique though.
Gotta figure out how to set these up lol.
