Completely concur, don't be naive and believe Verizon doesn't know EXACTLY what it's doing here. The only logical explanation really points to this being a marketing ploy in preparation for Nexus One for two reasons: 2.1 has now been released in Europe without issue, and 3rd party distribution issues could have been assuaged by slower release schedule. No further information leaks are occurring because VZW is already dangerously close to implicating itself in a class-action lawsuit here.
It's really unfortunate because many customers held out rooting their phones only to be jerked around by VZW's marketing whims. Forget about these idiots, root and ROM your phone to receive features you'll never get with the official update, and flash back to stock with SBF if you ever need warranty service. You'll be much happier.
