I hadn't checked to be sure, but why would the MacBook Pro use the integrated graphics chipset over the discrete graphics chipset (945G vs. 945P?)
They would not unless no other discrete GPU's significantly outperformed Intels offering, which they do now, so expect higher performance GPU's in MBP's, and cost savings integrated graphics in the MB, Mac mini, and some iMac's (perhaps all this round).
Also, why, when the next chipset comes out, would they use the integrated graphics one over the discrete graphics one? It generates more heat (even when the integrated graphics aren't being used,) and incurs extra expense.
More heat? How much? Higher performance GPU's general much more heat than either of Apple's current discrete or integrated solutions. It's merely a cost saving reason for using the integrated GPU (might be some minor space saving engineering cost reductions also).
Besides, ATI's chips do support multiple external connections, if Apple and ATI/AMD choose to enable them.
Apple does, what Apple does

, they don't even have an true HD res. screen on the 17in MBP, and you think they care if you don't have twin monitor capability on the portables? (rhetorical question, btw).
Hmm, so I read through the entire thread, and one thing I don't see is the typical skepticism about the source of the story. So, what if they're wrong, and SR Mac's start shipping in April (thought I think Think Secret is just grasping at thin air when they postulate about an HD screen 17in MBP annoucement at NAB)? Or there wrong and they start shipping (not just Apple) in June, when the chipset group finally is available in numbers. I would think every manufacturer will try to ship as soon as quantity is available.
Lets hope the next update to the MBP line includes a 160GB 7.2k drive option, like the one annouced by Fujitsu recently.
So the 45nm process is running a little ahead of schedule, or is right on time. Then we could see a MBP update to this by MWSF or earlier? Kind of makes you want to wait on buying any upgrade until then, unless you really, really need that SR chipset upgrade (assuming there are not many more irresistable hardware enhancements). If claims (recall the Merom was supposed to use less power) about 45nm process come to fruition, then you'd have a very significant longer run-time for the same clock rates.
