According to information gathered by AppleInsider, not only will new MacBook Pros hit later today, each come with new processors and a 4GB RAM minimum - the models will also include three (rather than two) types of screens:
"Glossy, High Resolution Glossy, and High Resolution Glossy with Anti-Glare."
So they're all glossy, but both the MBP 15 and 17 will have some sort of anti-glare option, even if there's no option to ditch the gloss altogether. We'll be interested to see how well that works. Now whether these processors are Core i5 (probably) or Core i7 doesn't seem to be immediately clear based upon the clock speeds also. If anyone spots another way to tell, share it in the comments.
And keep in mind, this is all unconfirmed at the moment, but AppleInsider's track record is about as solid as it gets this close to new announcements. [AppleInsider]
