The future of MacBooks? I doubt that.
The MBP is still a different class of Computers. They might loose the glass in a redesign for weight and a thinner lid. I wouldn't bet on it though. It just isn't necessary and although I don't like the shiny glass stuff, Apple seems very fond of it.
The basic MacBook looks a little pointless beside the MBA 13" which is almost as fast and in every other way better, but still Apple wants high margins but they won't remove the entry notebook from their product line. All the stuff that truly is any different than what we already had for years is the Flash drive and this one is way to expensive still for an Entry Notebook. They will still ship with standard hard drives and they probably won't sacrifice the optical drive either which means that the MacBook may get a new screen and case but that will have little to do with any "future" coming from a MBA.
BTW there is actually very little things that are truly new in the MBA. Flash has been soldered to pretty much anything for years it was in Netbooks before but always in too little size. It was only a matter of time till it gets cheap enough to build a serious notebook and Apple with some of the highest margins is obviously the first to make use of it. It isn't even a new thing to build a high end notebook. Sony did that but nobody would buy it for its price.
Apple pretends to be all innovative and people buy it but they really only just put together the tech that is available at any given time and they also have the brand to sell it for high price and with enough volume. Dell or Sony could build similar notebooks but they couldn't sell them in high volume at the necessary price. Thus they stick to a low development cost and simple principle and let others go first.
Dell Adamo is the best example they just cannot sell it at any reasonable price because there is no volume and all it is a little marketing project that probably yields little profit even at the price they sell it.
