It is especially because they are closely tied to the lore that they haven't released Umbra warframes yet.

This Excalibur Umbra Prime is only a misnomer that happened in China because they couldn't name it "Excalibur Prime" since that specific version of Excal is stricly for the players who bought the original Founder Pack.
