When can we expect the Mamba XL in stores again?

I am more interested in the current lead time in upgrading the MMMXL to VS2. I know that it states on their site that lead repair times are three weeks but does that also refer to MMMXL. Just don't want to be without a working ESC for too long. Considering I have to send it half way around the world, then for it to come back to me and if it was to sit there for ages would be really pointless. Would be nice if someone from Castle chimed in.
