It says HD locals are available in select cities. On another part of their site it says the only locals in HD they offer are WTEN-ABC and WNYT-NBC. Otherwise it looks like SD for the rest of the locals.
It also looks like the local channels only come in the silver package and up.
Just give the site a poke around and see what you find, or you could always call them.
You will only get 10 and 13 in HD on DISH, and you will pay extra for it, too. You also won't get the YES Network, in HD or SD, and when new HD channels come along, you'll wait 6-12 months longer than anyone else to get them and that's only IF they decide you are worthy of receiving them.
