First of all, Paramount Pictures has released an updated version of the Super Bowl spot with improved CGI, different font and better color grading.
Next, at this year's Cinemacon, Transformers 4 stars Jack Reynor and Nicola Peltz both won the male and female Rising Stars award. Roughly 15 minutes of the film was shown as well. There are descriptions of what was shown, but I will not be reading them or posting them here due to highly spoilerish content.
We also have three new stills from Transformers 4. One is of Sophia Myles, the other is of Mark Wahlber, Nicola Peltz and Bumblebee, while the third is a shot of Wahlberg.
Linkin Park is rumored to return to provide a theme song for Transformers 4. They have worked with Michael Bay and the Transformers movie franchise dating back to the first film back in 2007. Lead singer Chester Bennington was quoted as saying "We've been very fortunate: working with the Transformers franchise. It's been great for us. Transformers  is coming out this summer and it makes total sense for us to be a part of that as well. So, [we are] looking forward to [seeing] how that's going to unfold."
Also, a list of Transformers video games has been released that highlights a Transformers 4 mobile game, Transformers Angry Birds Go and a Transformers 5 game.
We also have a new poster that was just released yesterday. It features Cade, Tessa and the Nightship hovering over their house. The poster resembles the one made for the movie "Twister."
Finally, here is our first gameplay trailer for Transformes Rise of the Dark Spark. The game seems to utilize a lot of core elements from Fall of Cybertron and allows you to play as three versions of Optimus Prime. It releases in June.
