Honestly, I'd much rather see them do a quick live video and issue a press release announcing a 4th gate coming, even if it doesn't include any details, name, or date. All they would need is the confirmation that they're building a new theme park and it would suck all the air out of any Toy Story Land news.
Hey, you hear about Toy Story Land opening? Who cares, Universal is building a new park that's gonna be bigger than Islands of Adventure with new state-of-the-art rides! Wow, that's so cool.
