Default 10.1 with LTE???

I currently have a Galaxy Tab 2 10.1 with AT&T LTE. I am so ready to upgrade to the new Tab Pro 10.1; but the lack of LTE is keeping me on the fence.

Has anyone heard any rumors that an LTE variant is on the way?

The other option is using my S4 as a hotspot to provide internet while out and about. The only bad thing there is the S4 chews thru the battery when using it as a hotspot.
