I was looking through the "About PlayStation 3 (PS3)" screen (under System Settings) to see if it had anything related to Vita in there and I noticed something funny. At the bottom of the NetBSD section (which is rather long) there is "THE BEER-WARE LICENSE". Apparently the author only asks for beer in return. I sure hope Sony bought him a pint!
While I agree that most of the PS3 "updates" recently is pretty much useless (at least from user's point of view) as they're mainly trying to patch up all the holes but this one actually is major update as it brings overall support for Vita amongst some other minor improvements so IMO it warants the new major numbering as well.
I have no doubts in Sony though that they've most certainly managed to screw up this one in one way or another so we can all look forward to another update soon - will it be 4.00 (quiet) v2 or 4.01 or whatever ...
I agree with the most posts here. Yes, it's 4.0 because of the Vita support. But why did they add such "Health Warnings" now ? Isn't it pretty much useless now 5 years after the release of that console ?
And wasn't "British English" available all the time ? If not, it's really an embarrassing mistake on their side, not supporting every language of the most important language in the world.
why sony jump to 4th kind? where's 3.8 and 3.9 ? i thought 4.00 is for ps4.
It's not a decimal point, it's a divisor between major and minor version numbers. So 4.0 is a major revision, but 3.8 to 3.9 is a minor. But since they went from 3.56 to 3.60, it should actually be 3.6.0 ( majorrevision.minorrevisio.bugfixrevision ).
From a consumer marketing point of view, adding vita support is a major revision. It might not differ much from an API or a security point of view.
And why would the PS4 get PS3 firmware? Version 2.0 wasn't for the PS2...
