Hasbro looks to have decided to do their own virtual con called
Hasbro Pulse Con where they will be revealing new products for Power Rangers, GIJoe, Star Wars, Transformers, Ghostbuster and Marvel. They also will be offering exclusives which will likely be the ones previously meant for SDCC this year. The event takes place on September 25-26.
We should note that while it says the event is for for US & CAN fans only, we believe that is just referring to the selling of the exclusives which will take place on the HasbroPulse website. While Hasbro isn't really clear on how they will do reveals for this, I would guess it will be similar to other live-stream events that have been holding on their Pulse Facebook page where everyone can watch.
If or when Hasbro decides to clarify this we will be sure to update you.
