As noted by Peter Kafka over at All Things Digital, the location of the Amazon event -- Pace University -- is the historic, 19th century HQ to the New York Times which is said to be partnering with Amazon on the larger Kindle. That makes for a perfect symbolic bridge from old to new media. We'll have to wait and see if newspaper subscribers can be lured across.
Update: We have a reliable tip that Barbara Snyder, president of Case Western Reserve University, and Arthur Sulzberger, top man at the New York Times will join Amazon's Jeff Bezos on stage Wednesday. So it looks like a new Kindle focused on textbooks and newspapers is a lock.
