As for Roton, it might not fly in the RR configuration, but I'm betting that XCOR may migrate towards a HTLV design similar to Roton, since their current approach seems to not inspire the kind of investor excitement they need to fund a production run.
I seriously doubt that. I don't think that XCOR is in a cash-rich situation. When I said it was a deal for stock, I meant in exchange for a release of liability for Rotary Stock that was already owned by XCOR employees. But this is all speculation.

There's no evidence to support that. Why would they go from one approach that couldn't attract investment to another? It sounds more like wishful thinking on your part, rather than informed speculation. Anyway, their current approach seems to be successful, in that they are continuing to operate.
