13" is a goner. You have the standard plastic MacBook and MBA in that size. No need for a "Pro" 13".
We've had the standard MB and MBA since *before* the 13" MBP was invented. Not a goner, imho. Current rumours say they're gonna use Intel's SB IGP (which is apparently decent for an IGP) on the 13" Models.
Also the 13" MBP Entry Level is supposedly Apple's best selling model. I'd almost think they'll do away with the Plastic MB and drop the 13" Alu model to $999 USD before they get rid of the 13" Alu Model. (Even if they end up dropping the "Pro" Moniker and going back to 13" Alu MacBooks...)
15" -
- Removal of the optical drive. I've had my current MBP since Nov. of last year and have the optical drive . . . . once. Its finished.
- Dual 2.5" HDD bays. Configured differently, entry level will have 1 HDD.
- SB
- Higher Res Display
- USB 3.0
- New massive battery. Expect 18 hours out of a single charge.
- 10.7
- Expect air intake to come from one of the sides of the laptop (probably right) and a water tight keyboard.
Just opinion and speculation.
For sure opinion and speculation. This is *all* Op-Ed's basically.
😉
But I do think you're getting ahead of yourself. Possibly dropping the optical drive. 10.7 won't be out till the summer, and I'm sure the MBP will be refreshed before then.
USB 3.0 isn't supported in Intel chipsets yet, so that's not gonna happen till a late 2011 rev at the *earliest*.
18 hour battery is a little optimistic. I could see bumping the battery to 10 hours tops on only SB Graphics (with whatever discrete card they put in (ATI?) turned off).
Water tight keyboard would be awesome, but again, I feel like it's not in the cards.
All I'd bet on is:
- SB
- Integrated SB Graphics for 13" MB/MBP/MBA/Mini
- Some sort of ATI (Or NVidia? but Probably ATI) in the 15"/17" models.
- Higher Rez for 13". Standard "high Rez" in 15" (the one that costs more $$ now).
Some 50/50 bets I'd say are:
- Possibly a BTO option to replace optical with second drive.
- Better Battery life
The one thing I *wish* for is a matte screen option for the 13" Models.
