Leakster evleaks has let it out again about HTC W8, supposed to be Windows Phone counterpart of HTC One M8. They claim that HTC W8 will indeed come with dual-cameras seen on HTC M8. It will also have the Boom sound feature and will be based on A9 cortex processor, it seems.
HTC W8 coming to Verizon in Q3, running Windows Phone 8.1 and based on the A9. Look for BoomSound and Duo cameras to make the move from Android to WP.
While the teaser says it is coming to only Verizon in Q3, fans would expect a wider release.
