We don’t know if it will be Wazzy B or Billy G just yet but Forbes is due to publish its annual list of the richest billionaires in the world later today.

Gates beat Buffett by $40 billion to $37 billion last year after Buffett held the top spot for the first time the year before. Prior to that, Gates had been number one for the previous 13 years. US business channel CNBC has crunched some numbers and is guessing it’ll be Gates, followed by Buffett this year.

Edge of your seat excitement.
