ATM, it's much too early to even THINK about an ETA
As mentioned in another forum, "it will take as long as it takes" as far as getting our take on this legend up to our standards. Which as many of you know, are VERY high.
HOWEVER, it will be worth the wait.
The 500/series LA3A (still not posting it's official name, but it's a good one, hahaha) is probably the closest to release. Again, waiting or prototype iron to arrive for testing, chassis, etc, etc..!
