Again this is speculation. The phone is not finished yet. The Battery is better on dual core and when Honey comb is released it will work even better.. Weather you want to believe it or not the Thunderbolt is a upgraded Evo 4G with better Upgraded Sense Thunderbolt is old Tech. Dual sore is the Future. Whenever Bionic gets Honeycomb you will see the the real power of the Bionic. Don't get me wrong HTC Thunderbolt is a good phone but from what I heard from my friend from Verizon he told me to wait for the the Bionic it is a better phone... Also he told me if I can wait to 4th Q for the Verizon Atrix.. I am not waiting to the end of the year. So I will get the Bionic..
