It's 4 a.m., I just read the 6th mention of the same misleading story in the last 24 hours, and it's time for a rant.
Yesterday, several "independent" reports all claiming to arrive at the same conclusion at the same time (does anyone properly credit their sources anymore?) appeared on the web suggesting HTC had just (*gasp*) leaked two new Android 4.3 features: Bluetooth Low-Energy and OpenGL ES 3.0. And it's done so via a public meetup organized by the San Francisco Android User Group. HTC is so careless that they've just published not one but two unreleased features coming in the next version of Android and therefore protected by strict NDAs.
