You didn't want to wait until Kina to see what both companies may come up with?
The only change coming to the Move system is firmware and I'll be able to have that updated on the one I just bought. If Broncolor updates anything it'll be the Siros.
I have Profoto Pro 6 Freeze 2400 and Pro 7 2400 in the studio and D1s. Unlike your B1s the D1s have their shortest duration at full power.
For short duration on location I use Profoto Acute Twin Tube heads with pairs of Acute 1200s. When I need anything faster I rent Broncolor. This Move system will be the first of at least 2 to replace the Acute systems.
Profoto is chasing the only real market of any size that's left, wedding photographers. The B1/B1X, features like TTL and modifiers like the big umbrellas with the diaper on it target the un-skilled. So I have no reason to expect they'll introduce anything at the show that'll be of interest to me.
Broncolor introduces new products when they're ready. They've never waited for trade shows.
