If they didn't implement a discrete card with the HD3000, I don't see it coming now. Some of their notebooks retailed around $1000 a few years ago with that stupid GMA "leftover transistor repository" graphics chip. Given that the trend in general computing is toward integrated graphics, I doubt they'd go against that now. It's like how people have wanted a mid/mini tower desktop. If Apple was going to produce one, it probably would have already happened.
