A "reliable" source has claimed at Engadget today that the Barnes & Noble Nook will soon be on the receiving end of a "major update." Updated.

The update will address many of the quirks users have experienced thus far with the new e-reader. Topping the alleged list are performance improvements and a faster page refresh rate, both of which Wilson identified in his mostly positive Nook review earlier this month.

Update: Our own tipster wrote to say that this is 100% confirmed, citing an announcement that was made on B&N's internal employee network. We may have some visual proof shortly. [Engadget]
