This was announced months ago and doesn't even give any of the actual details we got while speculating a fuckton on information we never got.
It's "60 random cards" with no actual information on what the cards are going to be. Could be updated base set, could be 1:1 reprints with different backs, could be rebalanced shit a la D/P Charizard being basically a reprint of base set Charizard.
http://www.pokebeach.com/2015/12/pokekyun-booster-pack-image-break-starter-pack-officially-revealedThere's a second article showing the backs are modern backs, with sleeves to emulate the original back.
The article also has a 2500 price tag due to a misprint on a 30 dollar card. If you actually want a Base Set Charizard for collection, getting a misprint is the stupidest idea you can have.
