Alright folks this is what it is.
When you press the firmware name in the extras + info it's actually just a URL link to a page discussing the latest firmware, before the Denim announcement it would of shown the Cyan firmware but since Denim has been announced, they're going to talk about Denim. So if they ever have a new firmware after Denim announced, that page will be updated again with that firmware name on it.
It's as simple as that, if you didn't receive an update recently it's because you're not running on denim. Yes they still show that silly bug about Denim being installed to a lot of people but unless you're not running on Developer Preview and can make folders then you're not running Denim, simple as that.
