Regarding the newest update. SQUEEE! I don't have any clear favourite for most anticipated and those are some of the best covers BIg Finish have produced for Torchwood, however, The Hope might be one of my all-time favourites in general. It's also nice to see such a great balance with comedic Torchwood and the darker Torchwood, a 50/50 split it seems, something other runs haven't achieved quite like this one. I also appreciate the team-up of Tom Price and Burn Gorman, which I already thought they should have more stories together.
And finally, with the teaser we get in Torchwood news articles, Tuesday's being the most recent, it seems that 2 out of the 5 that are yet to be announced. The for certain one is regarding Opera, and no mention of that in any of the blurbs confirms this. The second may or may not be The Hope, but the news article says Owen is in prison and something at sea, so I don't think they are the same, which means more Owen!
If I had to guess what the last four are based on the little breadcrumbs we have, we have(in no particular order) 1. Torchwood Opera(Hoping it to be a Colchester-Price solo outing for the couple) 2. Owen in Prison 3. Likely an established team up, options being Jack and Ianto, Gwen and Rhys, and Andy and Norton(could be Driving Miss Julie) 4.A Yyvone or Rhys solo release, for no other reason than I'm guessing
