The bus can vary its speed as needed to conserve power. Makes me wonder if Apple will wait for this, but I highly doubt it. I think they will use it, but I can't imagine putting all other upgrades on hold for this. Even if on time for Q1 release, they won't see implementation before Q2 or Q3 I would bet...
Actually "Santa Rosa" is a platform specification. It is the code name for the upcoming 4th generation Centrino brand label. For a notebook to be a "Santa Rosa" or "Centrino Duo II" or whatever it ends up being called, it must include specifications that meet the "Santa Rosa" platform requirements and the manufacturer must pay licensing to Intel to use the Centrino marketing label.
Santa Rosa specifications thus far are expected to include:
1. Merom CPU (already available, faster chips coming in a few months)
2. Crestline chipset (available soon, supports more RAM and up to 800MHz FSB.
3. 802.11"N" WiFi - "N" draft WiFi is still not standardized
4. Bluetooth, Firewire400, USB2.0
Apple is *NOT* a member of Intel's registered "Santa Rosa" manufacturers. What this means is that Apple is probably not going to want the Centrino label associated with their products, nor will they want the Intel Centrino lable/badge stuck to their MB/MBP systems.
But a lot of us are hoping that since Intel has said the Crestline chipset would be shipping soon, to compliment the already available Merom, we'll see Crestline in the updated Mac notebooks within the next few weeks. If this is so, then we can expect to be able to install 4GB or more in a Macbook Pro and gain some other benefits. If Apple were to also include a WiFi chipset that supports a current "N" pre-version and support for update to the official version on approval, then the new MBP systems will be the equivalent of a "Santa Rosa" system.
What was posted above about the ntext Core 2 Duo update is essentially correct, but that isn't "Santa Rosa", although "Santa Rosa" can't exist without Merom. FWIW, there is already an "Ultra Low Voltage" version of Merom available, but few computer makers are using it. The next revision to the Merom CPU before Intel moves on to the next CPU model will hit sometime this spring and will bring the 800MHz FSB and should also have full SSE-4 instructions.
