Aer Iconia W4 is an upgraded Iconia W3 tablet with an IPS display and quite possibly a faster Bay-Trail based processor.
It comes with an 8 inch display and an Intel Atom Z3740 Bay-Trail processor.
Acer hasn’t officially announced the tablet yet, but Bouweenpc.nl has leaked a video of the tablet from an Intel event.
It still carries the W3’s 2GB of RAM and 32GB of storage.
Given that the W4 is running Windows 8.1, we wouldn’t be surprised if it reaches the market sometime around the Windows update’s launch in October.
