As far as we know apple has used a lot of hardware in its notebooks which was also used in pc notebooks. So my guess would be that the specs of the upcoming Macbook will be very comparable to the latest up-to-date notebooks from Asus, on of the largest hardware-producers, which also has factories in Shenzen/China?!
Let's take the brand new Asus N50 series,globally released 17/9/08.
There are two versions of it and the smaller one costs around 1000, and that's a good price tag because same hardware in an MB would cost us, let's say maybe around 1200-1300.
the N50 series specs are:
CPU: 2.4 or 2.5 Core 2 Duo
RAM: 2,4 max. 8GB DDR2 800 (official asus spec sheet says max 4GB, but a friend bought one and it eats 8GB)
HD: 320GB SATA
Graphics: 512MB NVIDIA GeForce Go 9300M GS or NVIDIA® GeForce 9650M GT mit 1.024 MB VRAM/
Display: 15,4" TFT (WXGA, LED Backlight, Automatic Lightdimming-Sensor)
Optical: 8 x DVD Super Multi D/L Double Layer
Interfaces: beneath other Gigabit LAN, HDMI, Bluetooth, Firewire 800, N-Standard Wifi
Camera: 2 Megapixel
I bet a horse that the specs of the new MBs are somewhat compareable to this. The may modify the display, exchange the GPU for cheaper Intel chips and give the lowend MB the 2.4Ghz and the highend the 2.5 GHZ CPU..
They simply cannot build in hardware, which did not exist until the beginning of Oct because they need to start producing and it must be current PC mid-range hardware otherwise the MBS will probably start shipping for 2k?!?!
Based on this specs, my guess for the MBP would be almost the same, entry RAM is 4GB, larger HDs and to differentiate from the MBs definitely with the NVIDIA GPUs. As Maximum CPU there will be the highest available Intel Mobile CPU today, the 2,8 GHz Core 2 Duo.
IMHO this hardware-upgrade from the current MBs would be enough for Stevie to go nuts at 14 Oct. again in the oldschool way... "AMAZING bright LED Displays, FW800, 2,5 GHZ , boomblabla..."
a horse for being wrong
