I agree with Elliot that the concepts remain the same. I believe however, that the way in which students approach those concepts will change; the "implementation" of how we teach those concepts will be dramatically different. In particular, I believe that Graphical User Interfaces and concurrency will invade the CS 1/ 2 curriculum out of necessity. If you want to do anything "fun" without attending to overwhelming petty detail, you need at least a rudimentary knowledge of these. Problems that require GUIs and concurrency for solutions also provide wonderful examples for teaching good design. The question for curriculum developers will be to focus on the big picture for a foundations course, taking from the modern technology only that which enhances learning concepts. CS 1 and especially CS 2, could easily degenerate into any of the following: A course on OO design, a course on HCI, a course on concurrency, or worst of all, a course on the nuance of a particular language.
I would hope that the workshop will spend time addressing the question of whether there is agreement on the big picture, as well as consider how modern paradigms (such as events and threads) impact how we can motivate the material for students. This does not mean we need to degenerate into language wars. Instead, I would hope that we can take seriously the profound impact the internet and the web have on our students' experience. We should ask how we can exploit their experience to make the foundational concepts relevant and meaningful.
