I think 'The Archive' is something more for the website than an actual product release. I think it's Rebel playing cards, Regeneration, Monument, and possibly decks of playings cards like the heritage series and maybe a download.
I think The Archive could be something like Denis Behrs Archive (maybe even powered by it) seen here. Basically, an online resource to log & find credits for sleights and moves, maybe even input new ones.
Of course, it could be totally different. What ever it is, I'm totally excited to see what it could be
Yeah I agree with LBarnes I think that Archive is not a trick but more of a tool that can be used on the site. Anyway I'm excited to see what they're releasing.
