Tesla (TSLA) will hold its Cyber Rodeo event on Thursday night to celebrate the grand opening of its Gigafactory Texas in Austin. The event could possibly unveil a few surprises, as well.

The EV maker announced that the event will be live-streamed at 10 p.m. ET on Thursday, on its Tesla Twitter account. CEO Elon Musk also tweeted about the event.

While the event is expected to be the factory’s official launch and also Model Y production at the plant, it does hold the possibility that much more will be seen from the electric automaker.

Tesla is producing a new variant of the Model Y SUV in Austin with a new 4680 battery cell and structural battery pack design, which may also give the EV new specs that could debut during the Cyber Rodeo, according to reports.

Speculation is also swirling around the potential of a reappearance of the Cybertruck, possibly in a production model, as the Gigafactory Texas will produce the electric pickup, Inside EVs reported.

The Cybertruck’s arrival has been delayed until 2023, so any mention of the truck would be noteworthy.

Inside EVs also suggested that the Cybertruck has almost 1.4 million reservations for the electric truck already, and the Cyber Rodeo may provide some clarity on when production may actually start on the vehicle.

Leaked drone footage captured by a Twitter user, and reported by Electrek, also revealed multiple other vehicles at the plant undercover that are yet to be revealed. A Tesla semi was also spotted.

An appearance from Musk is, of course, also expected at the event, much like was seen with Tesla’s grand opening of the Gigafactory Berlin in March, where the CEO acted as the officiant.

As of Thursday at 1:22 p.m. ET, shares of Tesla were trading at $1,041.66, down $4.10, or 0.39%.
