Given that none of the US carriers carried the octa-core version of the S4, I would make a strong guess that none will carry that version of the Note 3. Samsung doesn't produce these chips at a rate to keep up with demand, so they're using a very good chip from a company that can keep up with demand. Plus the Snapdragon 800 will be a better chip for AOSP development for those who like to flash custom roms.
