From what I've seen there are 3 batches of 2nd gen Cube, that ship with the following firmware:
PS7204/1044N (October 2019, initial release of the 2nd gen Cube)
PS7206/1098N (November 2019)
PS7229/1856N (January 2021, shipped with updated remote with channel buttons, sometimes called 2021 Cube)
Up until a month ago Amazon was still selling the 3rd batch with PS7229/1856N. I think this is the final stock. I doubt that Amazon made any new 2nd Gen Cubes in 2022, since they were already working on the 3rd gen Cube release. As long as the 2nd gen Cube is new it will ship with firmware older than PS7273 (March 2022), and this exploit will work.
The photos on the eBay box include the old remote without the channel buttons, so it probably ships with PS7206/1098N.
