I think that the threads that are currently in the reviews section should stay as is, however a new policy moving forward could be adopted.
When it comes to new releases, separate threads for speculation and reviews should be present. Once the kit is released, a new thread strictly for the review should be started (say, for the Moebius F-100). These new release review threads would ideally present enough material for presentation in the magazine itself (pictures of box contents) and discussion on the kit.
Retro reviews would ideally also contain pictures of box contents. History of a line of kits should contain pictures of box contents, but from experience I can tell you that unless you actually own all the kits it is difficult to do.
Just my 5ยข (according to the Government of Canada's suggested rounding guidelines)
