It's a matter of order of introduction, as simple as that. If the 1GB came earlier and now the 2GB was introduced, would you call it an upgrade? I doubt it, I wouldn't either. Going further, the GTX570 came a month after the GTX580. Is it a "downgrade" too? No, it's aimed at a different market (sorted by price and performance as the main differentiating factors).

How does 6950-1GB aim to a different marked? I can't see it, Could you please explain this with constructive arguments?
That one is even simpler, the 1GB is for 19x12 folks, the 2GB is for 25x16 and higher - the eyefinity folks. Yes, AMD can do triple monitors with just one card, so a 2GB card has bigger market than such card from nVidia. 2GB would also appeal to the OpenCL folks more than just 1GB. Sure, the 2GB can do 19x12 just fine too, but it's overkill, except for very few games currently.
