Okay - did a quick google, both "vizplex" and "e-ink pearl" are associated with the E-Ink Corporation, but they ARE different products. Vizplex is the older product.

At a guess, Sony didn't update their copyright notices on the new readers.

A Sony "branded channel product manager" wote back re: vizplex Vs. pearl:

"The new screen (on both the PRS350 Pocket Edition and PRS650 Touch Edition) is an E-Ink Pearl Display – specifically the E-Ink Pearl display is a Visplex V220 model

E-Ink Pearl display (Vizplex™ v220)
- Gray Scale : 16-levels gray scale
- Resolution : 800 x 600 pixels


The “Pearl” part is the marketing name for the screen
The Visplex V220 is the specific model of screen


The advantages of this new gen Pearl screen compared to previous Reader models are:
• Higher contrast
• Enable faster page turns


Mike - The customer is fretting for no good reason."

I guess that sums it up. Pearl is vizplex V220.
Just to clarify I do love the new Sony reader but I am a little disappointed that the 'white' part of the screen is not discernably 'whiter' than previous Vizplex screens. The black is definately blacker and the page turns appreciably faster though. And the Sony reader is beautifully built and full of great functions.

As far as I know, "Vizplex" is heavily trademarked, patented and what more have you.
Pearl is merely a new development to create a more detailed image with higher contrast, based on the same technology.
So, yes, although the startup screen mentions the Vizplex logo, the PRS-650 and 350 definately have the new Pearl technology inside. That's why I did the comparison between the 650 and the 505, instead of the 650 and the 600, cause both the 650 and the 505, like JSWolf mentioned, both lack a touchscreen layer on top of the screen.
