Twitter Joe posted this over on the Vz Forums today:
Quick update - we will not be changing providers per se, but with some new tech any particular data provider is less at the center of the story.
Rather our approach is to incorporate tons of TV data sources into one single feed that should be more accurate and more complete than ever. We are currently hiring and setting up our editorial team that will work all these feeds with a new tool that internally we call the "guide scrubber tool" (I know very creative name)... it's really neat tech that can sort through tens of thousands of data records pretty quickly to make sure you get the best on your TV screen... should be down to short weeks to turn it on. Will take a bit for the team and this tool to get its groove on... so expect gradually and steady improvements over the coming months.
