I didn't know there was someone else in here who talks to those guys on their forum. I was an early adopter for some of their parts on my VT. Had the 3TBS and TXE. These are, without a doubt, some of the best parts on the market for the VT, so I'm sure they'll do the ES proud.
If I am not mistaken the only parts that they will be offering for the ES are those that are cross-compatible with the VT for now as they do not have an ES for development. I've also heard through the grapevine that the 3TBS, XPVS and XWEK will all work with the ES and are all available now.
