BMX (@black_man_x on Twitter), aka Mobile Panda, has been a well-known and reliable source for information on Verizon phones for years. That's why several Android and news sites are reporting the information based off his Tweet. If he says something, it's pretty much given that it's true. Of course, like anything else, things do change, especially when it comes to technology and Verizon's notoriously lengthy testing period for updates. So the update could always be delayed. But BMX's information is almost always spot-on.
