As a graphic designer, I believe they are slowly preparing the Best Buy website to accomadate an update, lets keep a look out over the next few days if anything else might change in the Macbook Pro section of Best Buys website.
I am doubtful it will be March 9th, more likely March 16th or beyond.
A few things that point me to a mid to end of March 2010 release date is:
1)Best Buy stock extremely low...and when I asked one of the employees at the store, why they were so low, he was not sure, but never has he seen the inventory go that low, without being restocked after this much time. Macbook Pros have been flying off the shelves since June 2009.
2)The new Macbook Pro processors were benchmarked already practically over a month ago on Geekbench. Seems to me that 2010 production units are making there tours via Apple.
3)Cycle rate is due for an upgrade.
4)Now this mysterious logo on the Best Buy website, marketing is begining to surface, and that doesn't usually happen months before release for apple.
Thanks for listening, I am new here so go easy
