So, I have just seen this advertised based on the game...
20 packs per box, $150/box - has voice actor autos (meh) and sketch cards (cool) and lots of parallels as seems to be the norm for sets now. Also has what look like PMGs but only have the color at the bottom of the card, not the whole background.
Current release date of August 9th, ill probably pick a few of these up, much better option than the epack release imo.
