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.
Are we on schedule
Way ahead of it. Beta has been running for a week now.
Launch schedule at this point is almost entirely up to the community. We're testing hardcore now, but we can't magically create testers out of thin air.
Have been testing every day so far. Will be around today as well.
I try to call up additional German testers in my Blog (around 500 views a day) and international by twitter.
Testing runs smooth, I was always able to install the versions and get it running within minutes.
