I think gopunk's postcount per day has been increasing over the past few months, as I'm sure someone posted a while ago about him having 40 posts per day.
I have assumed that it has increased from 40 to the current rate over 4 months and if the rates continue to increase/decline for gopunk and NFS4 respectively then a quick graphical calculation (can't be botherd to work it out properly) shows that gopunk will pass NFS4 in around 320 days :Q
Edit: a little more accurate calculation gives 355 days, so my bet is on Feb 17th 2003
