Curious about Coral Princess Medallion Class Cruises

[hydrodriver831]

According to the Princess Website, the Coral Princess is due to start Medallion Class Cruising in Oct 2020.  My curiosity is that we have booked a 12 day Alaska cruise on the Coral for May 2021.  The cruise just prior to ours (4 day Coastal from L.A. to Vancouver B.C.) is listed as a Medallion Class Cruise.  The cruise we are booked on that immediately follows the coastal cruise is listed as Medallion Net Wi-Fi available, with no mention of Medallion Class.  Anyone have any thoughts as to why?  It looks like most if not all of the 2021 Alaska cruises are listed as Medallion Net Wi-Fi available.
