This has nothing to do with Verizon, I am pretty sure for some time it has been Google that has been against SD Card storage because it is "too confusing for most consumers" and had little to do with Motorola caving to anyone except their owners... Who the heck uses Verizon's services (ie. apps) anyway? Google has everything and it's free. Search around... Google has been trying to kill the SD Card in Android since mid-2011 when the original Nexus specs started leaking out.
BTW, I am not saying I agree in any way with them, just the opposite actually... just trying to point the finger where it should pointed.
I wouldn't be surprised if over the next few years, Google just removes support for SD Cards from the Android core, causing manufacturers to dump it completely or stay with an older version of Android to make it work, which would be a marketing disaster. So hopefully they will start coming with 64GB, 128GB or even larger internal memories. Remember if technology continues as it has in the past, the power of your cell phone will be about the same as your laptop in 5 years. I would love to have a 8192x4320 resolution 5.5" screen and a 16GB of RAM video controller with an 8-core 4GHz processor, 64GB RAM, 4TB of internal storage that read and write at 128GB/sec, and has globally available unlimited 100GB/sec data, voice, text, and video messaging for $30/month and a battery that only needed 8 hours of charge monthly... ahh... now I am rambling but that would be heaven! (or at least part of it!)
