It's turned out to be significantly more complex to properly package up P+ for console release than we anticipated. Basically, can't have 5 minute load times on console,
(But yes, we have some of our engineers working on it every day and it's getting done, should be submitted to Microsoft soon -- it's requiring some new technical pipelines to package it up in a manner that we can maintain without having every Xbox update be 4GB -- Xbox updates aren't packaged with per-byte differences like Steam updates, but rather only per-file which)
Looking forward to playing P+ on Xbox with ya soon,
