Schecter now has Simon's new UltraBass up for ordering (US only).
Note: The photo shows the black bass with yellow graphics, while the description says it's the yellow with black graphics. Not sure which is correct, but have contacted them about it. Will update if I get an answer.
Update (March 8th, 2017): Matthew finally got a reply about this, and it IS the yellow version, NOT the black as pictured. Here's the reply - "The one that will be available will be yellow with black graphics. We have the black one pictured because we don’t have the yellow one ready yet. There will most likely be a black version available later on." Thanks, Matthew.
