Thanks Bartheq for sending this in :P
A Polish site, PC.com.pl reported that the new Coca Cola bottle are labeled with XP"s logo.
Bartheq also translated following words from Polish that saids "This is authentic, scanned label taken from the new bottle - no fake. If you don"t believe it, visit a shop and find out for yourselves. Could this be that the new Coca Cola is also Windows XP Powered?" (Interesting... :D -Ed)
