Is there a list of Commentaries that were recorded but for whatever reason (loss of audio file?) the recording was lost?

There'll probably be completists out there that have to see it in every combination possible.

It'll be interesting to see if HFR takes off, or just feels like cheap video.

The mistake in all this discussion is assuming that what works for men (in regards to viewing women as sexy) also applies to women (in viewing men as sexy). Sexiness to a man is primarily about looks (youth, slimness, symmetry, health, fitness). Men don't care as much about the woman's social status, income, job, brain, etc. Women, on the other hand, have physical appearance as only one of many attributes. Consider it on a points-system where different attributes are weighted. Let's say anything over 100 points is deemed 'sexy'. For men, almost all the points come from the woman's looks: 20 points for long legs, 20 points for large eyes & lips, 20 points for hair, 20 points for flawless skin, 20 points for perky breasts, etc. For women, it may only be 30% weighted to men's looks, the rest coming from social status, wit, intelligence, leadership, humour, extroversion/confidence, positive outlook, etc. That's why withered old men can still get hot chicks because they make up the points in other areas. It doesn't work the other way around.

So equating sexualization of characters based solely on poses or revealing costumes is not a fair comparison.
