A MicroCenter staffer tonight posted new Apple model numbers that point directly at long-anticipated MacBook Pro updates. While just listed as "Mac systems" with Good, Better and Best trim levels, they have completely new model numbers and roughly correlate to the three 15-inch and single 17-inch MacBook Pros that currently exist. They also hint at price changes: while the base MacBook Pro would climb $100 to $1,799, the top-end 15-inch model would drop to $2,199 and the 17-inch would fall $200 to $2,299.
