The eventual second edition of the HTC One, codenamed M8, has appeared in the Wi-Fi certification database, carrying both 2.4 GHz and 5 GHz bands, as any self-respecting flagship these days.
This means we are one step closer to its release, and as far as hardware upgrades go, they don't sound very significant - Snapdragon 800 instead of the 600 in HTC One, an UltraPixel camera, and BoomSound dual stereo speakers. The kicker is in the design difference, though - still a premium aluminum body with undescored metal texture, but also a much larger, 5" or even 5.2" display. The software department is also likely to see an update to Android 4.4 KitKat with a brand new HTC Sense 6.0 skin.
Release date is scheduled for some time in February, which could mean the HTC One 2 aka M8 handset might very well turn out to be the first brand-name flagship on sale next year.
