I am looking forward to the High Definition coverage of the Winter Olympics. You will notice many HD events will be on NBC owned Universal HD channel. Many cable and satellite systems have added UHD to their lineup for the Olympics.
In the Detroit area, UHD can be viewed on channel 208.
Check out the complete HD listings for all events, via HD Sports Guide.
The listings are for USA stations only, but I do believe CBC in Canada will be offering many events in HD. Too bad Detroit area residents can't get the OTA (over the air, you know via antenna) feed from the CBC in Windsor.
