New MacBook Pros soon?

Whenever Apple readies a product refresh they typically constrain supply of the outgoing models in an attempt not to stick any retailers with a less than top-of-the-line unit.  It looks like the limited supplies of MacBook Pros might finally indicate that a refresh is due shortly:

“Apple retail partner and online reseller Best Buy has recently run out of 15-inch models, and lists on its online store wait times of one to two weeks for availability.”

We don't have any solid leads on what kinds of upgrades the new MacBook Pros might have, but we're expecting Intel's new family of mobile chips to be present in all models.
