WWE has announced on their website today that:
WWE Chairman and CEO Vince McMahon will make a major sports announcement today at 3 p.m. ET, streaming live from the digital platforms of his new enterprise, Alpha Entertainment.
There's been more that whispers going around the last several months that Vince is interested in reviving the failed XFL Football league. This could be about that, it could be about WWE going forward. However, if this were a WWE announcement they'd most likely use the term "sports entertainment."
