Received an email back from MTS -
Our mandate continues to be to expand our services to meet the needs of
our customers. Unfortunate, the process of expanding our HD Channel line
up has taken more time than anticipated. We will be adding more channels
in the near future, but there are many factors involved in adding a
channel that are beyond the control of MTS. As such, specific dates
should not have been released and we apologize for any inconvenience you
may have experienced due to information received in the past.
This tells me they probably aren't going to be making changes for months to come.
