I am wondering how the new prices for the arena season 1 gear are implemented. This gear has been moved from arena points to a combination of honor points and battleground tokens with the start of season 3, but to my surprise the references to ItemExtendedCost.dbc in the corresponding item entries from the item cache stayed the same as before and are still pointing to the old price (arena points). The in-game merchant however lists the sets with the new honor prices, so there must be a mechanism that overrides the extended cost entry in the wdb file.
Has anyone found out yet how this mechanism works? Might it be that Blizzard finally implemented a system to set prices individually per vendor instead of using a single global price?
