Well seeing as they are ALWAYS updating the bot and releasing improvements I would say that they "are working on" it as it appears in their list of priorities. Last time I checked Archeology bot is a shit bot that isn't essential to a high percentage of players here. Most of us bot for gold and leveling, so the bots that directly affect those are higher on the priority list than a bot that I'm sure plenty of us haven't ever purposely selected before.
Professionbuddy, Archeologybuddy and those really sub-niche bots are going to take much longer seeing as the amount of pissed off customers over those bots will be much lower than say Questingbot.
