I've noted in some earlier comments that I believe the CDX product, as a software solution, is likely under continuing revision. As such, CDX is likely to release an upgrade at some point in the future. When that might be, I don't know. But it is a logical progression for software, and CDX is software. I would suggest that one reason recent events have a theme of product evaluation and ascertainment of market viability could be that CDX is being tested regarding a newer version.
Just my wild opinion, and more speculation, for whatever it's worth.
Cheers,
