ATI makes the same amount of money on the cards. It's the vendors who will turn around and price hike the cards. If true, ATI get's hurt because less people buy the cards at first.
Well I guess if you think about it technically it's neither ATi nor the Vendor, but ATi's OEM partner (board manufacturers) that will be thedetermining factor. To ATi whether it's a 512MB or 128MB version makes little difference as they are shipping the chips, and it's the OEM partner who has to decide which card gets the added expense of the +256MB worth of memmory, and at that point it's a question of how much they can sell it to the vendors, wether the margin is enough to have large supply.
For ATi it matter in their BuiltByATi role, where they play all three of those roles, and they have to worry about those things.
I agree with you that e-/retailers could mess with this if they add price gouging to this as that would change the expected volumes from the board partners, and then they would change production due to limited turn-over, and like most things, the higher the volume the better chance to make the most profits from economies of scale. The X1800XT 512MB could be only slightly more expensive than a 256MB version if they move enough and then they'd be more profitable for Sapphire, Foxconn, et al to make and then they'd be more than happy to produce a ton of them, but initially no one is going to commit most of their resources to the elite very top of the line part so expect there to be less available, and depending on demand, you will see changes and potential shortages depending on how they move, and that will depend on a few factors inluding their choice of initial delivery method; and what may be good for ATi might not please the ethusiast market. Putting alot of 512MB in retail where 'Daddy' just goes out and buys the biggest/best for his kid or himself with little knowledge of the uses you might see alot of XTs move that way where if they were online you could meet the demand of people who truely want them because they know they'll 'need' them for what they want to do. The former may or may not move more chips and cards (BBA) for ATi, but the later is what keeps people in the forums and such happy and satisfied wth availability.
Of course if they've been able to build stockpiles, and production is full blown, then regardless of 'reasonable' demand there shouldn't be shortages of any kind, especially if they stockpiled alot in anticipation of moving production to the R580.
