Maybe you've had different experiences, but I've had very few problems with forward compatibility in all of the major browsers (IE/FF/Chrome), and I don't know why that would change going forward. Actually, I'd go so far as to say that if you develop your apps to work cross-browser, they're more likely to work in future versions of IE than if you specifically target your dev at a single version of IE. Also, just because I do 90% of my dev work where there are good tools, doesn't mean that I can't or don't test in IE 8- (depending on the target audience).
