There is a Canon Camera TSV on Dec 21st but I have no further info on what camera it will be. A few days before, QVC will send out an email about the TSV if you have signed up to receive TSV emails.
Edited: I see by looking at the Online program guide that QVC changed the date from Dec 21st to 20th. The Insider had the 21st.
I'm surprised they would do another camera since the last TSV was on Dec 1st.
