Next couple of weeks? I highly doubt it. In order for the G2 or N5 to receive LTE, all Samsung equipment in this area will have to be upgraded to support the new 3g NV(if they haven't been upgraded yet) . Without the upgrade, the phone will fall back to 3g only. It's due to the lack of CSFB(circuit switched fallback). As you stated, Roberts article is a great place to start if anyone is interested in the importance of this and the future of Sprint/tri-band devices. Basically, tri-band devices don't support SVLTE(Simultaneous voice and LTE) because the phone(s) only have one radio unlike previous devices(S4/Note 2/etc). Unfortunately, as ericwalton stated above, this area uses Samsung equipment and thus we are in a non incumbent market. The good news is Trenton /Tonya trial towers currently provide upgraded 3g/LTE and work flawlessly with the G2/N5/Galaxy Mega. Tri-county unfortunately doesn't have upgraded 3g yet. From what I've read, there's a high probably that when Sprint launches LTE on the west side of Hamilton, it will also bring upgraded 3g. Thus the new tri-band devices will work.
On a side note, in comparison to the S4, the N5 has a better LTE radio from my experience. It's likely the G2 will perform just as well.
