Coke does coffee

Isn't Coke already black for the most part?

On the surface, it sounds like it was made for me. My favorite soda with a bigger hit of caffeine? Sign me up!
It is supposed to be a mixture of "coke effervescence with coffee essence." The media hype is glossy - but what does it taste like? Cold fizzy coffee sounds odd at best... anyone remember Pepsi AM? The first person to taste it and report back gets an offical dispensation from the Sable Pontiff! (Look closely at the animated page - I love the fact that they spent a gajillion dollars on slick images and then spelled "effervescence" wrong...)
