I just don't see how S42 is going to be anywhere near the kind of high-fidelity masterpiece everyone thinks it is going to be on release. The Mo-Cap probably won't be. Now I'm no expert at all on Mo-Cap but listen to what Charlie Anson (an S42 actor) said during the filming for the MoCap stuff in Ealing studios (skip to 1:40)
He says the last time he did Mo-Cap was 5 years ago and it has 'evolved' since then and I think the choice of the word 'evolved' is significant. Well 5 years after that video was posted is the 'best case scenario' (aka won't happen) release date for S42. If the trend of before of Mo-Cap 'evolving' in 5 years happens again and I don't see why it won't then it's safe to assume S42 is going to ship with very dated Mo-Cap.
On a bit of a tangent it was bothering me so much about who that Charlie Anson guy was (it doesn't say his name in the S42 video) but it does have his name on the S42 IMDB

Here he is on Dragons Den (UK version of Shark Tank) pitching his idea for a cartoon drawing business. I checked google but sadly the business has closed.
