I have one of these new Sony PRS-350 and yes it does have a touch screen. However it does not suffer from the reflectivity issues of the old model.
Basically it has the same pearl e-ink display as the Kindle 3. The touch functionality is provided using a neat infra red system in the bezel. Here's a quote from a PCWorld Review.
"The optical-technology touchscreen uses infrared sensors to detect where your finger is; it compares that information against a matrix that identifies your finger's position and what action you are trying to accomplish, and then performs that action. The result is striking. I found the display brighter and dramatically sharper than Sony's previous touchscreen technology, with better contrast and clarity, as well as crisp grayscale images. Furthermore, I could make selections with featherlight touches to the screen. Previously, Sony used a resistive touch overlay on its Touch Edition PRS-600; the effect was unfortunate, with muted responsiveness, a persistent glare, and fuzzy text."
