2015's Super Bowl XLIX in UltraHD 4K?

Does anyone know if the 2015 Super Bowl XLIX will be broadcast in UltraHD 4K? Interestingly enough, I posed a similar question 3 years ago on whether the 2012's Super Bowl XLVI would be on TV in 3-D. And today, I'm in the same boat.

I recently purchased the Sony XBR65X850B 65" LED 2160p Smart 3D 4K Ultra HD TV. And though there isn't a ton of content out there (beyond Breaking Bad, House of Cards, and some Flowers and Forests on Netflix or a few free UHD movies on Amazon Instant Video), it's still an unbelievably good upscaled picture for standard 1080p cable television and Blu-ray discs.

I was hoping this year's Super Bowl XLIX would be broadcast in 4K (since it appears the 2014 Super Bowl on FOX was in Ultra HD) but everything I can find says otherwise:

• Mashable = The Super Bowl won't be broadcast in 4K
• Reddit = Will this year's Super Bowl be broadcast in 4K?
• Wall Street Journal = 4k source which isn't available for this year's Super Bowl 

Anyone have any better news for me?
