Officially they may be under the same continuity () but practically they are clearly very different and independent from each other. Even the only real link from one 'story' to the other, Dark Energon, is interpreted differently from WFC to Prime.

Sorry but I think that Hasbro is/was just shoe-horning things together that were never intended to be, common sense tells me that.

It also wouldn't surprise me if next week the same question is asked and we get a different answer altogether.
