[wp-testers] Avatars and 2.5

[Mr. Awesome]

Just curious, but didn't the Avatars get included into the 2.5?

I'm asking because I was kinda figuring that the comments.php files in 
the default and classic themes would be coded for Avatar display, or is 
this supposed to be a personal preference thing? Or, will the classic 
and default themes eventually be coded for it later?
