A:Answer I've been wondering the same thing. Finally caved and pulled the trigger on a wifi-only 13 inch Pro 360 last week and I love it. I just desperately wish they would release the 5G version like they'd promised. I have an unlimited data plan that this thing was made for.
About the only info I could find was from a few scattered Reddit posts with people asking the same question as you and a few responses from people who had spoken with Samsung customer service directly. They got answers varying from "No idea", to possibly February of 2022, but all seemed to explain the delay as a result of the chip shortage. Unfortunately I don't see that getting better anytime soon. Honestly, by the time they release the 5G version, it might already be time to release the second gen Pro 360!
