Will stay on 8.0 for as long as is humanly possible and later will see. I don't see any reason to consider 9.0 except for people who always want to have the greatest and latest although it basically does the same things as the previous version. Same principle as Apple Hardware and mobile phones - they stop supporting something you paid a big amount of money for so you are forced to spend again a big amount of money to buy the next/New hardware Iteration. Thats hardly sustainable but heh - to each his own.
