Goodbye to Kodachrome

I've never shot a roll of Kodachrome in my life - In fact, the closest I've gotten to Kodachrome is loving the Paul Simon song.  But I still have a lot of respect for how groundbreaking Kodachrome has been over it's 74 year life.  The numbers person in me is sad they didn't press on for just one more year so they could say that it was around for an even 75 years. Anybody want to take bets on how long Canon's CR2 file format will be around???
