I've found the best source of information is http://s4gru.com/. They aren't affiliated with Sprint, but they have better information that most of the customer service agents do. On the following page: http://s4gru.com/index.php?/topic/212-network-visionlte-deployment-running-list/ they list Colorado as a 4th quarter 2013 completion with no construction yet.
On the other hand, I've noticed that most of the cell sites around me are now showing eHRDP service, which is a precursor to the LTE buildout.
It seems that most of the regions have taken between 4 and 6 months to compete; since nothing has been started in Colorado as of Jan 17 2013, don't count on LTE to begin to show up til mid Summer, with completion by the end of 2013.
These are my best guesses based on reading lots of blogs, I'm not affiliated with Sprint, but I do live in Denver Metro and have an LTE phone.
s4gru.com has confirmed that Samsung (who has the contract for Colorado) has started working on Network vision in Colorado. http://s4gru.com/index.php?/topic/2824-paonia-colorado/page__view__findpost__p__79597
I have read multiple places that Samsung is ahead of schedule. Who knows when LTE will launch, but we'll likely have some before summer. Now, I only need to get a phone that supports LTE. Here is the thread for the Denver market: http://s4gru.com/index.php?/topic/2172-network-visionlte-colorado-market-denvercolo-springsgrand-jct/page__st__40
Does the Centennial area count for LTE coverage "around" Denver? Look for that purple spot, and keep zooming in.
Funny how the Sprint Call Center has LTE in Denver, apparently off Inverness Dr S near 25 & 470.
Does matter what they tell you when it is to be ready, it will be a lie just like everything else they tell you. All they want is your cash, and it doesn't matter to them what they lie about to get it. I was ready to move to some one that already had LTE service here, and their employee, not a partner employee said Denver would have it my the end of March, now they are saying they don't know when this will happen. I was stupid enough to believe them so I upgraded my phone and extended my contract. So March has come and gone and no LTE service, now they have no ideas of when other than it will be at the end of the project. Another lie told I would be able to keep my discount, even thou I don't remember how I got it in the first place but it was a company discount. Well screwed again by Sprint did not get to keep the discount either. Anyone not yet a Sprint customer stay away service sux in Denver calls drop constantly, and they lie. I wish I would have been smarter.
Yeah, the first tower with LTE was just accepted. See the post on s4gru.com: Network Vision/LTE - Colorado Market (Denver/Colo Springs/Grand Jct) - Sprint 4G Rollout Updates - Page 7
Now, this doesn't mean LTE is going to just start rapidly appearing everywhere. It will likely take a while for other towers to get completed and come online. It could be just a week...or many weeks. But that's a good sign that progress is being made.
I don't live in Denver, but I saw this article recently. Sprint has apparently confirmed LTE is being built right now, and it's doing a "from an outside-in" strategy. Here's the article:
Thanks for posting and I want to allay your concerns right now. Denver will be getting LTE, it is a huge market as it is a gateway to the American west and a major American metropolis. I can't guarantee you a date but we will get there, hang in there please!

Thanks for posting. A perfunctory review reveals Vision architecture will be built in Key West in the next 6-8 months. When did he service start to deteriorate? Does it fluctuate as per location and times of day or is the service level constant? Please let me know.
