I know this is an unpopular view but the MBP updates everyone is hoping for is a long way off. I cite two commonsense reasons:
1. iPad HYPE will be on maximum for the next few months. The last thing they are going to do is release the iPad, blitz the media about it, and then release new notebook computers...
There is a reason record companies do not release two hit singles off the same album at the same time...you know?
2. If you have been following the feature list on MR you will know the next gen notebooks will probably have the following: i5/i7 technology, 8 GB of memory, revamped/hybrid (auto) GPU, BD Optical Drive, USB 3.0, perhaps a new form factor and the list goes on. (The list might be bigger or smaller but you get the idea)
Does anybody here really think Apple is just going to 'take down the store' for a few hours, put all of this online and then come back up with just a new front page? Really? Really??
That is a HUGE update for Apple's notebook line and then are going to have some sort of press briefing about it.
Problem: A MBP press briefing conflicts with the iPad at this point.
Moral of the story: Don't hold your breath for a new MBP until the iPad hoopla dies waaaay down.
