Official invite shows a previously unseen Asus ZenFone 4 device, launch set for August 17

Front and center here is the company's new Asia Pacific brand ambassador, actor Gong Yoo, who has previously been teased in a contest on Asus Taiwan's Facebook page. So seeing as the company has gone to such lengths with this marketing campaign, we're inclined to believe the August 19 date will be a local launch in the Philippines only, while the August 17 event will play the actual host to the world debut of the ZenFone 4.

But what's most interesting here is probably the invitation itself, which quite shamelessly displays one of the company's upcoming devices in full view. We imagine this is the regular ZenFone 4, as the pictured device's body doesn't feature a camera bump like the ones we've seen in the ZenFone 4 Max and Pro.

We're also not yet clear on whether this will be a single device launch event, or if Asus will finally debut the entirety of the long-delayed ZenFone 4 series. Whatever the case, we're expecting an eventual release of five different models: the eponymous ZenFone 4, a variant called ZenFone 4V, a high-specced ZenFone 4 Pro, as well as two mid-rangers, a ZenFone 4 Selfie, and the already unveiled ZenFone 4 Max.

However, it's worth mentioning that the company has previously had plans for a separate launch event in Europe, according to a leaked invitation for a September 21 event in Rome. So even if we do see a debut of the whole lineup, there's a fair chance people outside of Asia will have to wait more until they can get their hands on the devices.
