I really, really, really, really hope they make an Aluminum MB or even a 13.3" MBP. I don't want 15 or 17 (not to mention the absurd price) and I'm not going buy a plastic laptop. I suppose that's hoping for a bit too much from an incremental update huh?
I'm thinking not so much on this one, but hey anything could happen. Would be a nice surprise considering I'm waiting for the a major update to buy 1. Out of curiosity, wouldn't they usually release a major redesign at a convention (WWDC, MWSF)?
Also by looking at the buyer's guide you will notice that most updates occur in May. Think about it, kids graduating, getting ready to go to college with lots of money from graduation gifts make this a prime time to buy. Why wouldn't Apple release it in May? Also I think we will be seeing decreased waiting time between updates because Intel.
Though I will say that the website is pretty shady though.
The 3G iPhone is going to be the BIG hype for Apple this year. So, it makes sense to release the new laptops before the new iPhone. If not, the hype of the new iPhone could drown out the new laptops. On the other hand, the hype of the iPhone could help sell the new MBs, right before a new school year.
I highly doubt Apple would release new MacBook and MacBook Pro models this soon. I mean, they took the time to comlpetely redesign the pages on their website, dubbing the previous refresh as the "New MacBook, New MacBook Pro, etc." After all that they are going to redo it again after only three months? It would be really confusing to me why they would tell customers they are "new" three months ago, then "new" again tomorrow, it's not good marketing in my opinion.
