60 is max (so far). The auction house in WoW is more like an actual auction house than in FFXI, where you actually place a bid and you can be out-bid by someone else. There is a buyout option, though, which is similar to FFXI's AH in that if you pay the price the seller puts the item up for, then you get it right then. Unlike FFXI, the buyout price is clearly visible in WoW, instead of having to guess at it. =)
