Chris from ThinkPenguin elaborated on this here:

This is what he said:
"I may have answered this already, but here is why we don't have the new
models released. We're working on a dual-band 802.11n router. It's done.
Problem is we need $$$. It's something like $30,000+ USD for just this one
model which we don't have at the moment. Hopefully I'll pull the cash
together shortly for it. There has been a lot going on and the profits on the
new router will be seriously lower making it even more difficult to make
work. The lower end router would be easier, but the work on that isn't
complete.
I should also point out that it's unclear right now... still... what is going
to happen with the FCC when we go for certification. It can be certified and
they can still fine you into non-existence. I don't support this sort of
violence and theft, but there aren't enough people opposing mindless
regulations and government in general as it stands. The solution to this
immediate problem as I see it is to lock it down metaphorically. By that I
mean we won't add digital restrictions, but we will be forced to remove
upload/flashing functionality to comply with the rules. I probably can't say
more without creating a legal issue. However the complete set of sources will
be available and I'll leave it to your imagination what good that would be
for a locked down device or a device for which there is no sane means to
flash. Encouraging others to violate the law in other words would create a
problem."
