To clarify, the only reason there was an "early attendee" exclusive last year is because of the unspecified problems they weren't able to make the SNAKEs part of the full set. The SNAKEs were not made as an attendee exclusive, it just happened that way. To quote THE Mike when asked the same question:
"NO. 100% without a shadow of a doubt - NO.
As I've stated MANY times. That SNAKE was supposed to be with the con set. Problems happened and we had 50 done. So, it became a bonus item."
