You are misunderstanding. I am not talking about licenses. I am talking about (as yet) un registered serial numbers for EZKeys 1 sound modules that were purchased from Thomann (or any other reseller) http://Toontrack EZkeys Sound Expansion – Thomann United States (thomannmusic.com)
An owner of these serials can use them any time. But since EZKeys 2 will be coming out on May 16th 2023, any unused serial numbers will no longer work for new EZKeys 2 sound modules. However all EZKeys 1 sound modules will load in EZKeys 2.
It is very unlikely that Toontrack will release any new EZKeys 1 sound modules before May 16th 2023.
I am offering the serial;s for grabs if you PM me a reasonable offer. If you bought the above 3 serials bundle they would cost you $228 (or $76 per module). I offering the serials in batches of 1, 2 or 3 based on anyone's offer (firts come firt serve).
I'm only offering these for those that don't have some of the current sound expansion modules to get them before May 16th 2023, because I already own all 17 EZKeys 1 sound modules. On May16th hey will be useless according to Toontrack.
