According to Roland Quandt from German website WinFuture, Acer is preparing four new Windows Phone handsets that are expected to be announced during an IFA 2015 event, which takes place from 4 to 9 September.The pricing, availability and other details are unknown at the moment.

The new devices are expected to arrive with new Windows 10 Mobile operating system, since Microsoft will announce it not long after IFA, in November. There is no word on what to expect from the phones and what audience will they target. Considering the company has only one Windows Phone 8 device and it is entry-level device, we could see mid-range phones.
