There was too much official smoke on black/yellow for it to be nothing. The painting of the J Note, the redesign of the training facility, the website redesign to be black and yellow, the officially licensed Jazz gear that was black and yellow....

But I also think it all met some really bad reviews and there's a chance it's all been scrapped now. But a redesign was promised (though they've spent the last month walking it back and saying it's more a tweak than anything) and so they're trying to figure out what to do now after their carefully-crafted plan fell apart in a hailstorm of internet mockery.
