The background is not the character you use the most. They are unlockable ones you can select, and there isn't just one for each character. There are others that aren't necessarily any character, like hexagons or the current background from the beta.
It is. Seth Killian confirmed it in the interview with PS Blog. He said the background menus appeal to the character you've been playing with the most. That was why Jak was in the main menu and it was orange with ships flying in the background because it's from the Jak series. If it were Drakr, it would be his color with a sandstorm in the back.
Is the final menu build actually the FINAL menu?? I don't remember but I could have sworn the final menu would have hexagons. Can someone clarify?
If not, the word "final" is losing it's value T_T
I dunno. But what do you mean Hexagons? Like, in the background?
I think they meant something like this:
Except, not MLP... hahaha
