The news comes from The Android Report, the same source who leaked the alleged cases for the device the other day, and comes accompanied by a picture of the device's packaging (seen above) — meaning there's a fair chance this rumor is actually the real deal.
Launch delays are all Asus seems to be about these days, though: the ZenFone ARwas expected to come out in the U.S. last month, following its unveiling all the way back in January at this year's CES, while the company's upcoming ZenFone 4 line will be launching later this month, four months after it was initially scheduled to. Still, missing the launch window by three days won't be such a big deal, unless the rumored launch actually turns out to be the start of pre-orders.
As for why this is exciting news, the answer is simple: the ZenFone AR is actually a pretty interesting device, as it's the second phone ever to support Google's Tango augmented reality platform, as well as the first one to do so while also being compatible with the Google Daydream virtual reality platform. And while its AR abilities will most probably be overlooked thanks to Apple's recent interest in the field, it will be interesting to see how the two competing platforms will fare against each other.
