Cablevision gets official with four NBC Universal HD channels

We absolutely knew they were on the way, but if you needed a little affirmation from the carrier itself, Cablevision has announced today that it's adding four more high-definition channels to its iO TV lineup. Effective immediately, customers can expect to see Bravo HD (745), CNBC HD (771), SciFi HD (748) and USA HD (738) in the EPG, bringing the grand total to a very respectable 68 high-def networks. There's no word on when the next batch will arrive, but why not enjoy these for a minute before hankering for more?
