Yes these would be absolutely perfect and i intend to use these for the next generation. The BFL chips would require a lot more development because of the flip-chip package.
Awsome news!

I think I will buy some chips via groupbuy... do you have any idea how much chips per board will needed?
Some people say 4, some people say only one and doesn't depends on maximum sockets - I think it depends on the individual pcb design - in this case, do you have any plans?
(I know you have a lot of work to do, but this is very interesting - hope also I can order my bitburner XX soon

)
Maybe there could be things like these:
BitBurner X V2 (bitfury edition)
10 x 5 GH/s = 50 GH/s
BitBurner XX V2
20 x 5 GH/s = 100 GH/s
BitBurner XXL
xxx x 5 GH/s = xxxx GH/s
....cut
Then - for small to medium order amounts actual acquisition would be done to multiple locations using intermediaries who will do assembly, certification and will have end-user support for the devices. For bigger quantities it will be possible to get chips directly.
....cut
Perfect
