Considering there's a 30 day announce for the snapshot after the testing phase, the shortest delivery we can expect is at least 2 months upon release of the testnet.
BM expected the release of the said testnet before the end of July... Give 2-3 weeks more just because there's always delays... I would say mid to end of October.
If things don't go as planned, it could delay for a month or two more, bringing the release of 2.0 by the end of the year.
