I have yet see any spec detail of US version, but I found one blogger claims Japanese version spec released by DoCoMo states it's LTE version has S4 snappy, 32GB internal, and 2GB RAM.

It also mention that US version will be same.
So it becomes like,
International : Exynos 4 core, non-LTE, 1GB RAM, 16/32/64GB
Japan & Other with LTE : S4 Snappy, LTE, 2GB RAM, 16/32GB
Korean : Exynos 4 core, LTE,
I don't know how accurate his information is, but I will be happy to have Dual-core S4 and 2GB RAM over International one.
When will AT&T release this for us?
