could be soon - the chips are ready

It's possible that the Intel Mac could be announced at MWSF in January '06.
Apple's been telling developers exactly which chips will be in the first MacIntels, and they are currently available chips.
The clue is that the DTK documentation is telling developers to use 32-bit and to replace AltiVec code with SSE2 vector instructions - not 64-bit and not the newer, higher performance SSE3 vector instructions.
If we look at Intel's current and future chips, we see:
- Xeon (Paxville) - 64-bit, SSE3, dual-core (due by end 2005)
- Xeon (Irwindale) - 64-bit, SSE3 (current)
- Pentium 4 - 64-bit, SSE3 (single and dual-core)
- Celeron - 64-bit, SSE3
- Pentium M (Merom) - 64-bit, SSE3, dual-core (due by end 2006)
- Pentium M (Yonah) - 32-bit, SSE3, dual-core (due by end 2005)
- Pentium M (Dothan) - 32-bit, SSE2 (current)
Note that the current "Dothan" Pentium M's are the only CPUs in Intel's current lineup that only have SSE2 - therefore Apple is clearly telling us that Dothan-based products are on the way.
Which systems would get a Dothan? Mostly likely the iBook and the MiniMac. Apple could relatively quickly release those two systems with Dothans - all the chips are ready and they don't need to wait for anything on Intel's roadmap.
However, a Dothan-based iBook would kick the G4 PowerBook's butt on lots of tasks. Apple, therefore, might be inclined to hold off on releasing the MacIntel iBook and MiniMacIntel until the PowerBook could have some "power".
What do we see in the roadmap - dual-core Yonah should be ready around MWSF'06 time, also dual-core Xeon!!
So, at MWSF'06 Apple could announce any or all of:
- iBook Dothan - immediate availability
- MiniMac Dothan - immediate availability
- PowerBook Yonah (dual CPU, single dual-core) - available in limited quantities, or "soon"
- iMac Yonah (dual CPU, single dual-core) - available in limited quantities, or "soon"
- PowerMac Paxville (64-bit quad CPU, dual dual-core) - also limited or "soon"
By waiting for Yonah in the PB, the problem of the iBook eclipsing the PB disappears.
Will Apple do iMac? Probably not. The Dothans and Yonahs would outperform the G5 on some things, but if the video apps aren't well-optimized for x86 the G5 might be better for those. There's also the minor embarrassment of going from 64-bit back to 32-bit - but we all know that 64-bit brings almost no benefit to the iMac.
How about the PowerMac quad Xeon.... IMO it would be a good transition system for early adopters and developers - Apple could continue to sell the G5 systems for legacy apps until the transition is complete. However, using the current Xeon chips might be too large a serving of crow for Jobs to swallow - so I don't see this as too likely.
(There's also the issue that OSX86 is 32-bit only, so trying to hype a 64-bit hardware system with a 32-bit O/S might seem cheeky. Oh wait, Apple did that all through Panther....
