BB team was "working" on site before V2 and they had like 2 months "working", now with V" looks like the date to open the site again is far far away, if we are lucky maybe for chrstmas they will open, but i don´t think so...
Back on Christmas? It would be more than 2 months, I think betterbets can do it faster (if they are really working on it). Afaik betterbets's dev is a great well-experienced person, logically it wont take too long time for them for migration to Moneypot v.2.
