For the most part, these look like some awesome cash shop items. Hopefully arenanet makes tons of money selling what are basically like digital booster packs for the minis/items/dyes/etc. The mystic key is making me raise an eyebrow, but I can't pass judgement until I get more information.
Gems look CHEAP too, which is fantastic. Although honestly that is probably subject to more change than anything in those screens. That price is going to be all over the map at launch unless arenanet is going to take a very hands-on approach to the economy. Remind me to stock up on Jute scraps when the game launches.
They also have one of the best looking auction houses I've seen in an MMO lately.
