That is just speculation on your side. More probably, reading the forums, they realized, that people don´t grasp the idea of modules. They don´t grasp the idea of a playtest... and to reduce negative conversations on those forums, they decided to go to a more private enviroment to do the realy playtests.
I hope, I am right, but this is only speculation on my side (backed up by a L&L a few weeks ago).
Also their first draft on the bard and also on the sorcerer and warlock were quite neat. Especially the warlock had the right flavour... I hope we see the preview soon in a L&L (we were promised to gest some specific previews in L&L articles).
