Wel, let's see... if such a "reputable news site" existed with this info, then it wouldn't really be news to any of us. Just responding to rumors posted on XDA and on Reddit, and parroted in the Mega-Thread, which, as we all know, are not necessarily reliable sources. So therefore it should go unspoken? Hmmm...
It wouldn't be the first time a company did this. Verizon knows they have a superior network. And frankly, I'm pretty confident that I wouldn't switch to Sprint's unlimited data if VZW suddenly cut off mine at the knees. It all depends on how many GBs Verizon is offering for how much $$, what Sprint's network coverage looks like whenever that happens, and of course what my monthly data usage works out to be.
And Verizon might wait for network congestion to become unbearable before striking out at unlimited data plans, or might decide that it's less risky to make a move sooner while they do have a coverage / LTE advantage. I can guarantee they're testing the waters right now with their 2x deal, trying to figure out if there's a "sweet spot" that reels in new contracts. Maybe they'll play with price. Maybe they'll delve more heavily into throttling / pay for speed plans. Maybe they'll leave us Unlimited folks alone until we die. (Wonder if I can pass it down to the kids?!?)
