Once again, an anonymous Best Buy employee has come through with some new Zune HD details, and this one's infinitely more tangible than a computer screen. Pictures of an official display sent to Gizmodo seem to all but confirm its street date will be September 15th, just one week past what we heard yesterday. Pre-orders require a $25 deposit, but as for the full price, the best we've got right now are those $220 / $280 estimates from yesterday.
Update: If you needed any more reason to take September 15th off from work, Buy.com has a Zune HD countdown leading to that very day. Huzzah! Thanks, Stephen!
