Note that that's before the official start of campaigning. During the last campaign it went from something like 35% to 48%, partly due to how godawful the Unionist campaign was.

I don't even know who they might get to do the No campaign who has any credibility in Scotland. The most sensible option is probably Ruth Davidson, so the most likely choice is someone like Blair McDougall. Labour will probably have to spend all their time trying to avoid letting Jeremy Corbyn say anything on the subject.
