[citation][nom]JacekRing[/nom]I liked the part on how Verizon wants to switch to VOIP, using their 4G service. Consider that I don't get 4G in a lot of places here in PA, and they charge extra if you go over their 2 gb limit (I'm still grandfathered in the unlimited plan) that will bring in a lot of money to Verizon. As with VOIP will get you over that 2gb limit quick.[/citation]Voice over LTE just means they'd no longer be requiring CDMA for voice. So they could sell you a phone with no CDMA, LTE-only, and you'd have access to voice and data as normal. You'll still use minutes for calls for the forseeable future unless you used a third party VOIP service yourself. So no real changes from the end-user's standpoint.
The reason they haven't done this already is that their network won't be 100% LTE capable until early 2014 more than likely. As much as I dislike Verizon's prices, they've been very aggressive about rolling out LTE. I'm very much enjoying their LTE service at my house and around town, it has been very reliable and consistent.
Down the road they could even reclaim some bandwidth by shutting CDMA off entirely, but this won't happen until even further down the road as it would render older phones useless and they'd have to hand out an awful lot of new phones. So they're going to wait on that until most of their customers have upgraded by choice or by necessity (damaged/inoperative phone).
