Im sure someone else will have found this already, but go to
http://store.apple.com/us/browse/home/shop_mac/family/macbook_pro?mco=MTE4NDY
Then go View - Source. This brings up all the HTML formatting for the site.
Now scroll down to the code for Macbook and Macbook Pro's.
There is the following code inplace, just hasnt been activated yet.
<img src="http://a248.e.akamai.net/7/248/2041/1466/store.apple.com/Catalog/US/Images/dept/new.png" class="new-icon pngfix" alt="NEW">
This is the code for the NEW icon (go to the new.png url) to see what I mean.
This code is in place ready for use on the Macbook and Macbook Pro products only.
Safely say this is what will be new on the 14th.
Cheers, Sorry if this is a repost.
