My B.2600 is paid for at this point. While Sweetwater has a listing for it, it's marked as "Check with your Sales Engineer" since it's going to be a bit before N.Am shipments. But if you DO check with them, you can set up and prepay an order. It's also worth noting that Thomann is saying "6 to 8 weeks" at present for the next B.2600 batch, which probably is the date it'll finally drop worldwide.
As for the BCR32 (that's the name of the new sequencer), it also seems a bit aimed at Korg as well. After all, they also dropped a 4-channel sequencer in the past few weeks...but it's not the Zaquencer, which already has a devoted following and a sizable user base. And while the Korg SQ-64 has some sizable differences, there's a lot of similarities between the two of them. But if you were to just view the situation in terms of sequencers that're appropriate for an ARP 2600, the BCR32 much more resembles a synth's step sequencer than the SQ-64. You've got the knob controls per step, for one thing...plus the Zaquencer firmware was more performance-oriented than most sequencers of that sort.
Not sure just yet, but Behringer may have whomped them twice. And with Korg's vague stumbling-around in the past couple of years (which seems to be getting worse...$1400 green MS-20, anyone? Anyone? Buehler?), maybe it'll take a few head-shots from Shenzhen to get them to snap out of that.
