According to a report by Engadget, it is said that the European version of the Nexus will have multitouch while the one in US, Singapore and Hong Kong will not have multi touch. This seems to be untrue as Google staff has responded at the Google support site.

Just to clarify, we are shipping the same Nexus One to the UK as we are in the US. The phone does not include multi touch. Hope that helps. http://www.google.com/support/forum/p/Google+Mobile/thread?tid=36be77e62d8dfdf4&hl=en
