Can that whole schedule be published? 
11th of April - 17th: Multisig
18th - 24th: Client for hardcore users (I don't like bells and whistles that eat 100% of CPU)
25th - 30th: Testing of the whole Iota functionality
1st of May: Holiday
2nd of May: Release of beta version
This is my personal schedule that is not coordinated with the Foundation that (maybe) planned Grand opening with fireworks and barely dressed girls serving cocktails.
The holiday here is from 30th April to 2nd May, so personally I prefer the release on 3rd of May.
