Billboard preempts still unlaunched Lumia 928, mentions best low-light camera

Looks like someone let the cat out of the bag early. The oft discussed but still officially unlaunched successor to the Lumia 920 Windows Phone from Nokia has apparently been put up in a blllboard for all to see. The Verizon billboard shows the Lumia 928 product shots that look similar to previous leaks but the real gotcha here is the claim of 'the best low-light smartphone camera.' Has Nokia managed to improve on the already stellar camera of the Lumia 920, will we see more PureView magic once this new device is released?
