References to unreleased hardware?

[darwinian]

I was looking through a system profiler file, and I found some references to various pieces of hardware, some of which certainly do exist, but some of which don't ... can we sort out which is which?

MacBookPro5,1 (Late 2008 MBP)
MacBookAir2,1 (Rev. B MBA)
MacBook5,2
iMac9,1
MacMini3,1
MacBookPro5,2
iMac10,1

They appeared in a strange section of the system profiler output with a line called:

+-o Root <class IORegistryEntry, retain 12>

Configuration files buried within some versions of Mac OS X show evidence that the next iMac and Mac Mini will indeed be based on the NVIDIA MCP79 chipset. Apple recently switched their MacBook, MacBook Pro and MacBook Air models to the NVIDIA chipsets in October. Amongst other benefits, the new notebooks have much improved graphics card capabilities, which make them more suitable to take advantage of OpenCL technologies coming in Snow Leopard.

Apple will apparently be bringing these improvements to both the new iMac and Mac mini. While many have expected the iMac to receive these upgrades, the fate of the Mac mini has been less certain.

A configuration file found in the Mac OS X version that ships with the new MacBook and MacBook Pros reveal entries referencing an unreleased "MacMini3,1" and "iMac9,1" models. The relevant lines have been excerpted here:
The CFG_MCP79 appears to refer to the NVIDIA MCP79 chipset found in the newest laptops. The findings were originally described in a forum post that we've subsequently verified.

What's a MB 5,2; MBP 5,2; and an iMac10,1? Interesting that the iMac has the 9,1 and the 10,1 listed here already, since neither appear to exist.

I fail to see the surprise here. I mean, there will likely be further revisions of both iMacs and MacBooks in the future. It's not exactly a world-changing revelation.

A few new model numbers

MacBookPro5,1 (Late 2008 MBP)
MacBookAir2,1 (Rev. B MBA)
MacBook5,2 ???? (Current MacBook?)
iMac9,1 Upcoming dual-core iMac??
MacMini3,1 Upcoming Mac mini
MacBookPro5,2 17" MBP??
iMac10,1 28" iMac Upcoming quad-core iMac??

Somebody please correct me if I'm mistaken anywhere. Let's try to sort things out.

What's up with the 2's, anyway? Doesn't a second number change mean a more significant change than a first number change? But the notebooks just had a big update.

What's a MB 5,2; MBP 5,2; and an iMac10,1? Interesting that the iMac has the 9,1 and the 10,1 listed here already, since neither appear to exist.
