HTC have just announced the Desire 600, a dual SIM, quad core, Sense 5 equipped mid-range handset featuring Blinkfeed and BoomSound (but no Ultrapixels), to be released in Russia, Ukraine and MEA (Middle East / Asia).
Forfeiting the HTC One's Ultrapixel camera for a 8MP conventional snapper, the device has a 4.5" qHD SLCD 2 screen and a 1.2GHz Snapdragon 200 quad core processor. An 1860mAH battery (removable) powers the device, which features 8GB onboard storage and a microSD slot. Given that the device doesn't include LTE, battery life should be pretty good!
The device will be available in the markets above from June 2013.
I think it looks pretty good myself... it'll be interested to see the price. I assume it's not coming to Europe as it would encroach on the forthcoming 'HTC One Mini', aka the M4.
