I think these dates are going to be "best case", at least for the
Brick.

I'd think that we would have seen by now a more detailled spec on how
this brick will look like if the design was mature. Manufacturing
leadtime for this type of equipment is typically 8-10 weeks for
production quantities. To ship by June, this means that PowerFlarm
team should have a frozen design mid April. This is 4 weeks away hence
my doubts.

I am hoping that my PowerFlarm brick will be filed in June but I would
not be surprised if I am still waiting for it in August (along with
the NK Vario).
