Take all of this with a grain of salt:
For some time now the staff of TFNation have been dropping cryptic hints of something big to come. Fans have speculated that this year's TFNation could have an officially sponsored exclusive product.
The Twitter account of TFNation mascot Genny has tweeted about the resemblance of Brunt to the Mark V Guardian Droid from the Marvel G1 comic, though no identifiable plastic has been leaked on Chinese social media.
Now, the TFNation Twitter account has separately tweeted '10 years', '2 months', and '25 days', which has recently been interpreted by fans as the length of time between the finale broadcast date of Transformers Animated, 23 May 2009, and the first day of TFNation this year, 16 August 2019.
What could it be?
