I hope 2.0 hits at least a few weeks before PL comes out?
They said it will come out before hand, but they also said in their post "No sooner than 90 days" which 90 days from that post would be 10 days before PL, so my guess is that's the day it comes out which gives them 10 days to test and hotfix any issues that come up between 2.0 and PL.
But I want to point out, that saying the new update will be "No sooner than 90 days" doesn't mean it comes out in 90 days so its my guess that they will release on that day to give them the time to patch if needed. BUT as it's only a guess 2.0 could potentially be the same day as PL or anywhere in between especially. if they need to push it to iron out some issues.
