I don't think this necessarily signals the end of Matrix ITA. In fact, QPX Express and the Matrix are completely unrelated.

And, "QPX Express was a lower-touch way to let companies start experimenting with QPX without needing full on biz-dev contract cycles", per someone I know with some inside knowledge.
