I know it will be close. From what I understand, Zero had about a 1% share last year... and it had been growing at over 30% during the summer of 07. If it grew that well all year, it would've ended up with a 1.3% market share... which would almost certainly put it in the Top Ten of 07.

Hopefully, they'll add a caffeine-free version this year to keep the momentum going. I definitely see more people buying it lately (particularly guys).
