Maybe the episodes will be slightly longer, balancing it out. Something similar happened with The Killing, and they made their last season of 6 episodes longer, I think they were 1 hour long instead of the usual 42~minutes.
It's the same sort of time as 10 episodes, but, might be more convenient. Or maybe that was just a product of being on Netflix, where they don't need to be 42 minutes to allow enough advert breaks in an hour slot.
Still, more is better than nothing either way.
True, six is better than nowt. At least they can fashion some kind of ending, even if it's a bit compromised.
Alas, so many TV shows that have some creative thought put into them get cut short due to poor ratings, but reality show nonsense goes on and on.
