Steve Cook's wholesaling course the same or updated?

I hope someone has some insights into this. Back in January 2005 I purchased Steve Cook’s “Wholesaling For Quick Cash” course and noticed that he is selling this course with a new cover on it. Has the course been significantly updated since I first bought it and, if so, are there new techniques in it that aren’t in the course I originally bought in 2005? I’m wondering if I should purchase this course again or if it is just the same course that I already have. TIA.

I don’t have his 05’ version but I do have his wholesaling for quick cash version 2.0. Its packed with info and I believe in his intro that he makes a comment how this version has much more info than the previous additions.
