Shouldn't they be showing up soon? A series?

Should be showing up at the last week of this month.

What are you talking about?

you know, the customized logos?

You mean these: http://www.google.com/doodle4.html , http://www.google.com/doodle6.html , http://www.google.com/doodle7.html , http://www.google.com/doodle9.html , http://www.google.com/doodle10.html ? There are only 4-5 scenes and the last one should be on January 1st.

It'll probably start of Christmas Eve... and end before new year (because new year has its own separate one)

Looks like Google Earth is the first product team to celebrate......
