I've thought about this a lot. How much of my love of photography is for the pictures themselves and how much is it for the process of developing and printing film? My guess is it's about 50/50, but if you remove the film half, then that's half my love of photography gone. As many others have said, I'm not interested in crop sensors. A 50mm lens is a 50mm lens to me. So, if film did go away, I'd probably save my pennies and try to get an M9 or some other full frame option for my M lenses (assuming there are more choices in the future). For an SLR, I'm still hoping that someday someone will put one out that doesn't have all the bells and whistles of high end full frame dSLRs but is still robust and hopefully slightly smaller. Like a digital Nikon FM (not necessarily with a mechanical shutter).
Still, having said that, I'll keep shooting film until the only thing left is cheap, sketchy Chinese film that I have to buy on eBay.
