Well, when I sent an email to CZ USA asking that very question, here was their response. Italics, bold & underline are mine.
Loren,
The Bren 2 for the US civilian market is years out due to the Czech military having contract precedence from our manufacturer. From there, civilian variant production will begin and eventually include the US market. We have no information regarding specifications, ETA, production numbers, or pricing at this time.
Thanks,
