Developers are already working on ports today. Many apps will be in the submission queue before the iPad hits the stores, many of which will be live on the day it does. I was under the impression that the app totals were under 26k. I'll revise my estimate to a few months then, thanks for the specific number. There are some apps that aren't suited to the iPad, but a large number of existing apps will make very interesting ports once re-imagined for the larger screen and additional input methods.
