HTC Zeta rendered, rumored to pack 2.5GHz quad-core CPU and Ice Cream Sandwich

Ready for today's grain of salt? We just got handed imagery and specs of a possible HTC device in the works codenamed the Zeta. It's a quad-core handset, much like the Edge that was leaked last week, but it has a much faster 2.5GHz APQ8064 CPU along with 1GB of RAM running the show, on a 4.5-inch 720p HD display. According to our source, the uniquely shaped smartphone will come with Ice Cream Sandwich pre-installed with Sense UI (version 4.0 wasn't specified, but we'd be surprised to see any lower on an ICS device) and have 32GB of internal storage space, an 1,830mAh battery, Beats Audio, Bluetooth 4.0, an 8MP rear camera with dual LED flash, 1080p video capture and a 1.3MP front-facing cam. Dimensions? We have those, too: the Zeta is said to measure at 109.8 x 60.9 x 9.8mm (4.32 x 2.4 x 0.39 inches) and weigh 5.15 ounces (146g). Pricing and availability are still unknown, and we're still digging for more info. It certainly has an intriguing look; the sharp corners would be a huge departure from HTC's recent design choices, though it appears to have HTC's signature unibody build in the back. So are we just looking at a cool concept or is this the next flagship phone? We're hoping it's the latter.
