I agree brekkie. Possibly because they're colours seen in the original form of the logo.
As they did the bare minimum to celebrate Christmas over the decade (though the eventual snowman ident was lovely) do we have hopes for anything this year?
I'd personally prefer animated idents like the stings, though the blocks in an ice cave would be different.
They will reuse last years with the current look shoehorned in, Easy enough to break part a 4 logo.
