HTC may have poked fun at its competitors' plastic flagship devices in recent past, but it looks like the Taiwanese company will again be offering one soon. And no, we're not talking about the Butterfly line here. According to a reliable source of ours, HTC's upcoming "M8 Ace" -- which was teased by @evleaks earlier this month (as pictured above) -- will actually feature a plastic unibody instead of aluminum. Additionally, the M8 Ace will apparently pack almost identical specs as the Galaxy S5, including a 5-inch 1080p display plus a 2.5GHz, quad-core Snapdragon 801 SoC. But here's the twist: HTC's phone will be much more affordable, which could pose a huge threat to Samsung if true.What remains to be seen is whether the M8 Ace will also get the M8's Duo Camera feature. According to an earlier rumor by Chinese site TMTpost, a phone matching our source's aforementioned description could launch next month for as cheap as CN¥3,000 (about $480) unsubsidized, which would be quite attractive; though we'll have to wait and see what the camera situation is.
