MBP`s will get added USB/ESTA combo port.
That would be *VERY* nice, but for some reason, Apple hasn't done eSATA so far, so I don't know.....
15" will get the i5 standard (with BTO i7 ).
Darned well better!
17" will get the i7 standard.
I'm also leaning toward not just the Arrandale i7, but even the quad-core Clarkfield i7. If they're going to be doing discrete graphics anyway, why not go whole-hog?
Both will get more ram , and maybe HDMI ( ? ) , but no BD-drive as standard.
More RAM? Doubtful. They already ship with 4 GB standard, max 8 GB. Unless they throw in two more SO-DIMM slots (hey, HP did on the Envy 15,) they won't be able to go any further.
HDMI? No, they've settled on mini DisplayPort. At *BEST*, they'd come out with an official Apple-branded mDP-to-HDMI adapter or cable. But as other companies already make such a device
cheaply, it's probably not a market they'd go in to.
As for BD.... That, to me, is a tossup. Apple complained of licensing, well, BD has theoretically fixed that. Also, there is now required managed-copy, which makes ripping to the computer officially supported. Finally, Apple has deals for "Digital Copy" on DVDs and Blu-Ray discs. So this could be a possibility now.
