I was wondering if anybody new more about Sprint's 2010/2011 Android lineup. I ask because I am considering switching to Sprint to get the Evo, but am certain that I will want to upgrade when newer phones begin to come out (particularly those with dual-core Snapdragons) later this year or next year. I do not want to switch to Sprint for the Evo if it is going to be their only device that is ahead of the curve for the duration of my new two year contract. Any help is appreciated. Thanks.
