After the fans have been discussing and asking questions on various forums for some time, Marcus from the developer team comes put with this great Q&A on the dev blog; a total of 20 questions on everything from combat to character creation.
About shopping:
"There will be no special trading options. However, more item tiers are planned, because we also think that currently there’s not enough item variety to keep the item progress interesting. This includes literally all kind of items from armor pieces, jewelry, weapons, shields and the prefix/suffix probabilities and combinations of magic items. The design goal is to eliminate the "Oh, it's the same dagger AGAIN"-feeling. Also, merchant offers will be a little more individual, fitting the merchant’s location and background. For instance, the chance to find fire based equipment will then be higher at dwarven merchants."
