Hot on the heels of a thoroughly-previewed 5730 XpressMusic, new images of the luscious upcoming Nokia E75 have surfaced along with some new details on its guts. It looks like Nokia might have found a new form factor du jour – the E75 is one of three unreleased handsets that feature the new slim side-sliding QWERTY design. We’re not complaining, mind you, but so far the N97 is our favorite of the bunch in terms of design. Having the 0-9 keypad is nice but we prefer more screen real estate on a side slider rather than a tinier display that sits way off center while typing. Moving along; the E75 pictured above is the Germanized version featuring a QWERTZ keyboard but the core specs that have been confirmed will apply to all versions. Confirmed items: 2.4 inch screen, 3.2 megapixel camera, HSDPA and Wi-Fi. It’s not much but it’s enough to whet your appetite for now. The timing of this leak makes us wonder if the E75 is destined for an official announcement at Mobile World Congress – Nokia would surely want to steer clear of any big Nseries news that may detract from its coming flagship N97 so it makes sense. Whether or not MWC is the target, expect more E75 news to come around well before the show kicks off. Hit the jump for more pics.
