I really don't see the point of view many are ranting about.
Here's the list (I can think of) that have been official statements from HTC or VZW regarding the TBolt.
1) CES 2011: HTC shows off the TBolt. States it's heading to VZW in Q1 2011; so by end of March.
2) Jan 2011: A limited preview page for the TBolt goes up on VZW. Let's you sign up for future updates. States no date range for release.
3) Feb 2011: VZW updates the preview landing page, and starts ad placement all over the internet.
And that's it! What is VZW doing so wrong here? Keep in mind, YOU are choosing to read websites about future and upcoming phone info, before the carriers are officially unveiling them. Rumors, supposed release dates, etc... it's all info being brought to by someone OTHER than VZW / HTC.
All VZW wants to do is make certain their network & the device are solid and ready to go. Create some buzz with well timed ads, and have the phones start selling like crazy a couple weeks later. Buzz too early gets forgotten and/or slows current phone sales.
