I just stumbled in here and haven't read beyond the first post, but I saw this:
I made a new pet Friday night and threw it into the rift shortly after midnight (so Saturday morning, technically). I still have the event up from when my pet returned (as RA-001), and it's timestamped as 7:00am Saturday. That's definitely not 48 hours.

No it's no longer a 48 hour wait for Rifted pets. It was at first because it was new and they wanted people to wait a bit before finding out how pets come back out. But then it went down to about 12 hours. That's how long my pet took to get Rifted. Congrats.
