Its quite easier for Disney to do these announcements than it is for Universal. Disney announced quite a bit of stuff all on the same day. Now whereas it seems omfg Disney is doing so much, its more so they just dropped 8 press releases all at once to a crowd of Disney loving fans.
Universal could do that, however, way less impact as no one is a Universal Studios Films/Park fans. These would lead to a lot mroe stuff being missed in opinion.
