3d is a gimmick that gave me a headache when I had the Evo 3d. The 3d effect was pretty cool, but just added depth and had nothing popping out.
TitaniumSS, are you in a LTE area for Sprint?
I saw in one of the many videos I watched were someone looked at the useable amount of storage on the phone and it showed 20 GB. I couldn't tell if that phone was already clogged up with people adding pics and videos or not, but since it was a non carrier version, it didn't have carrier bloatware on it. That'd be 12 GB worth of stuff pre installed on the phone, no wonder there is no 16 GB version!
I already have a 64 GB microSD card, but if Sprint carries it, I will go for the 64 GB version, but I won't be too upset if I land up with "only" 32.
