I honestly think the auction system will depend on the item system in the game. If it is like FFXI where a Haub always has the same stats, I have a feeling it will be similar to FFXI. If items can have the same name and different stats, we will most likely see something quite different from FFXI.
You still want to charge something so that people don't just use it as free storage space by posting all their items for 10,000,000 so no one can actually buy them.
I'm hoping that inventory in general isn't as limited as it was in FFXI. Buying another content ID, or a real life 20$ (or however much that token cost) product to increase inventory is a little user-unfriendly. Simple things like gear not being removed from the inventory when equiped, were PS2 limitations I bet. I hope other PS2 limitations like the 7 slot limit will be removed, as this is ancient technology. Not the cool crystal powered kind either...
I hope we see search options that allow to search by name/stat/price vs just a slot type with a list. I think seeing list prices would be an improvement over guess and check style buying, but it does remove the kind of 'action' feel FFXI had.
As a side note...
Did you lose faith?
Yes, I lost faith in the powers that be.
But in doing so I came across the will to disagree.
And I gave up. Yes, I gave up, and then I gave in.
