Have you been looking at the Spanish version of the AoW forum as well? Could possibly be something on there.
Otherwise, yeah it could be delayed again... Starting to turn into a bit of a pain. I know they were upgrading to be able to produce kits at a faster rate, but surely that means they should have atl east been producing some in the mean time.
Also remember Felix said that the June 4 estimate was meant to be conservative date so it wouldnt' need to be pushed again and they should really come out earlier. So I guess there may have been another delay we haven't heard about..
