Simon Furman updates his blog with information about upcoming story lines for the UK Transformers: The Movie Magazine released by Titan. Future issues will lose the Protoform modes and switch to the movie's Earth modes. Since they don't want to contradict any future movies or IDW comics, the Magazine will instead focus around moments of the movie that can be further expanded on. Furman gave the example of the story for #7, "Starscream's Militia" which will take place shortly after Megatron falls, but before Starscream retreats.

You can see the blog entry here, it may be a bit spoiler-ish for some readers of the magazine.
