Asus wants to sell 5 million ZenFones this year, ZenFone 6 and ZenFone 5 are available now

The ZenFone 6 costs around $230 (6,990 TWD) in Taiwan, while the ZenFone 5 is priced at $166 (4,990 TWD). Both were launched in Taiwan before being introduced in other markets because this is Asus’ home country. China is probably one of the markets that will get the new smartphones next. According to Focus Taiwan, Asus CFO David Chang “predicted” that 5 million ZenFone handsets would be sold around the world before the end of 2014.
Asus also has a ZenFone 4, which features a 4-inch WVGA display. This is obviously cheaper than the other two ZenFones, and should be available starting this month, too.
