I think its a good move, we all had guessed at least some of the plot points that are mentioned.

Also Hunter never mentions the outcomes of any of his experiences. All we really know is that Hunter/Sunstreaker fight Scorponok, see the Dead Universe, ally with Grimlock and fight a full Decepticon alliance, and survives.

We know no details, outcomes, or consequences. Hell at the end of the "-tion" series it could very well be Sunstreaker vs. the Decepticons!

All it's done is spell out all the future plot points that have had plenty of clues and hints left around beforehand.
