Okay, but it turns out that we're talking about two different things here.
ePBT uses (or used to) Gateron blanks for their printing process. The Gateron blanks are well-liked, and represent good value. There have been some rumors that ePBT hasn't been using those blanks in recent batches.
There are a number of Chinese manufacturers who are distributing keycaps, and I've seen that some of the different companies seem to be using the same blanks, the same molds. Probably Gateron, but I don't have measuring equipment to tell. Again, some of the Cherry-profile keycaps from different dye-sub companies look like they are using the same molds.
The other issue, though, is the new 'Gateron profile,' which seems to be something new and unique. 'Gateron profile,' in this context, is not a reference to the Gateron blanks used by ePBT, but an entirely new profile that is property of Gateron. These keycaps are not commonly available yet, so details are scarce.
