Well the 360 is running on 512 so I could easily see 1 gig for the next gen consoles and if we are extremely lucky 2 gigs however there will not and I repeat will not be one with over 2 gigs.
Well a total of 2gb would only be a x4 increase from this generation. I don't think we would be "extremely lucky", I think that's the least they will need realistically, 1gb of vram and 1gb system ram.
Isn't 1gb of ram what most PC games need for 1080p ? So allowing for console efficiencies, 1gb vram could be enough to last the whole of the next generation, although within a couple years after launch, 1gb vram could start to become limiting in the way that 256 did this generation. 1.5-2gb vram would be a comfortable amount, leaving plenty of room for post processing and image quality. On a console, the textures would look incredible with that much vram. But it's got to have balance with the rendering power. A mediocre GPU with infinite ram is worthless compared to a strong GPU with a tighter ram budget.
Historically 2gb total ram next gen would be a low increase. Most typically, next gens launch with 8 times the memory as the predecessor. So that would be 2 and 2 in a discrete setup. I think that would be ideal, but depending on what type of ram and how much of the budget they allocate to CPU/GPU, 4gb may be too expensive if they're aiming for a low price point, say a $400 launch sku.
To reiterate my prediction, 2-4gb of total ram is the sweet spot. Any less is definitely not enough and any more is probably too expensive and beyond the point of diminishing returns.
However, the next gen Nintendo system very well may have less than 2gb. Knowing they like to make a profit on hw from the start, 512/512 seems possible. But even such a low figure would represent more than x10 increase from Wii. It's doubtful Nintendo's internal game programmers could even make use of more ram than that. They make fun games, but they're not known for pushing the tech envelope.
