Future Android Builds

Hello everyone. I have a quick question. I am expecting to get the motorola droid for christmas this year ( I know I am ) and know that it comes with android 2.0 already installed. I've heard that there's an update (2.01) that applies to the Droid and was wondering will I have to do an update to receive 2.01 or will it already be on the phone? Also, as computer and tech savies, it is safe to estimate that google will continue to develop their android os to later versions (2.1, 2.2, 2.3, etc.)
Do you think by the time these versions are released (1 or 2 years maybe?) that the droid will be able to receive those updates? I have seen new phones (HTC) that come out with ver. 1.6! , an old version. I'd really hope that the new android giant phone can handle future upgrades.

Thank you!
