The new iphone will undoubtedly be awesome, imo. It will remain the more polished of the 2 and will app store will not get any weaker.
All that said, android as an OS is amazing and will undoubtedly continue to evolve at an exciting pace and continue to be amazing

If the iphone comes to verizon, i might consider it at some point in the future. But for now, i'm feeling like I have an amazing phone (the moto droid) on a killer OS, backed by the best cell carrier and an amazingly smart company called Google
Let's all be thankful for the options and competition cause it only makes things improve faster.
