I personally would prefer separated tabs for specific inventory type items (ie: armor, food, currencies, etc) for version 2.0, over the inventory bag system that's being advertised. I have always loathed bag systems in other MMO's, tabs in a centralized inventory would be so much more game-pad user friendly.

I can easily understand why each category may not be able to have it's own individual inventory limit as that would require greatly increasing per character and retainer the total amount of items which could be stored and may also negatively impact certain players whom need to hold more of a certain item (food for culinarians for example). However, both could be avoided if the concept was similar to how Sabaku_Usagi described, which if i understood correctly we all maintained the current 200 limit inventory and the tabs merely were for ease of searching through it. Course, I'm not a programmer, let alone a game developer so I don't know what strain a system like this would have on the game, but if it were possible that's really what I'd like to use.
