Industry sources are now saying that ASUS' upcoming ZenFone 4 lineup will start shipping sometime in August. While that is next month, ASUS first expected to launch the lineup four months earlier. The exact reasons why that happened are unknown, but it will have though competition as many phone makers are expected to introduce new models in the third quarter of the year.

The lineup is rumoured to include at least three models - ZenFone 4, ZenFone 4S and ZenFone 4 Max. The latter was already announced, but only in Russia where it is selling for RUB 13,900 ($230/€200).
