It depends on your region. In general these things take some time (hours) to go live globally to all enabled regions, and are done carefully. If you come back tomorrow or in a few days it's more likely to have reached you, assuming you're in an eligible region.
It's probably best to wait until the UI actually tells you Bard has been updated to Gemini Pro. Previous Bard updates have had UI announcements so I'd guess (but don't know for sure) that this would have similar.

I don't understand how anyone can see a delayed EU launch as anything other than a red flag. It's basically screaming "we didn't care about privacy and data protection when designing this".
I think that's one interpretation. Another is that proving the privacy and data protection aspect takes longer, regardless of whether the correct work has been done. Another interpretation is that it's not about data protection or privacy, but about AI regulation (even prospective regulation), and that they want to be cautious about launches in regions where regulators are taking a keen interest.
I'm biased here, but based on my general engineering experience I wouldn't expect it to be about privacy/data protection. As a user I think things like Wipeout/Takeout, which have existed for a long time, show that Google takes this stuff seriously.
