Microsoft/OAI and Google have been doing those (often sudden) announcements back to back a lot. Bing Chat/Bard, Sora/Gemini 1.5, some other I don't remember, and now another. Not surprising, trying to out-hype the other, but Google's always coming out worse, with either no product available and just a showcase (if it's a real, working product and not made up), or unusable/unmarketable (Gemini's image generation issues). It looks as if they're stumbling and OpenAI just runs circles around them announcements wise, and there doesn't seem to be any suggestion that might change anytime soon.
