Come April 1st I will be eligible for a 2 year upgrade from my current phone. I will no doubt be staying with Sprint, due to their competitive call and data plans, as well as the fact that their current line up of phones is showing progress. Which brings me to my question... Come April 1st (which is less than 3 months away), should I upgrade to the HTC Hero (which I have been researching heavily the past month and I am absolutely in love with) ... or should I wait for the next big smarthphone to come out on Sprint? I am pretty much sold on Android OS, so will there be another, upgraded, Android device to come to Sprint soon? In 3 months, will Sprint have released something new and bigger than the HTC Hero?

Thanks for advice and insight!
