Switching to Android.

Hi there Android Army!

For the past few months I've been considering switching platforms ( I'm an iPhone user since the 3GS ). I've been thinking about getting a Nexus device ( I really don't want to buy the One X, nor the S3 ), but my real issue is: Should I get the Galaxy Nexus now, or wait until the end of the year for the new version(s) ?

Thanks for the help!
