I just received confirmation that tomorrow's OLN High Definition feed of the game between the Rangers and Flyers will be on INHD, channel 206 for Comcast customers in the Detroit area.
update 8:57am, penguinsfan, a frequent reader of Kukla's Korner, has just pointed out upcoming games are now listed on the INHD website. So it looks like anyone with INHD will get the games in high definition. See the comments section of this post for more information.
update 12:56pm, I have had a few emails asking about Center Ice on Directv. It appears it will be offered.
