There is already a multitouch developer library available that allows developers (at least on the latest Cyanogen build) to work with multitouch gestures and input, and this is on my "aging" G1. AFAIK, there has not been a single non-multitouch-capable Android device released yet, so yes, it could be a simple OTA update to enable it if Google finally mans up to Apple. Regarding the "app limit", there is already a confirmed plan from Google to release an update for Android that will allow storing downloaded apps on the SD card as well as onboard memory.
