I'll be honest, when starting this thread I thought that G5 had already begun and that more material had been released. That is my mistake for not doing any research before posting.
Thank you all for your replies. I've enjoyed reading them, and it has given me some good insights into the current perception of G5. As I now know there is another very similar thread to this one as advised above by CloudMistDragon we should probably move the discussion over in that direction
