The Samsung Galaxy S II continues to roll-out, with pre-orders for the smartphone on T-Mobile kicking-off today. As it does so, it’s likely work is already well underway on its successor, the Galaxy S III. We’ve been fielding rumors of this phone for months now, going all the way back to April. Most recently, we’ve heard some really impressive specs suggested for the handset, including a quad-core 2GHz processor and 1.5GB of RAM. Then again, the source behind that info was a bit suspect, and some of the details, like 1280 x 1024 non-widescreen display, sounded just nutty. A new leak suggests some very different specs for the S III, and these sound a little more plausible.

This slide shows the evolution of the Galaxy S series, leading up to the future S III. Here, the phone is depicted as only a dual-core model, running at 1.8GHz with an Exynos chip. On the other hand, it would have more RAM than earlier rumors suggested, with a full 2GB. The resolution of its 4.6-inch Super AMOLED Plus display is given only as “HD”, but it’s likely we’re talking about a 720p component. Also look for a 12-megapixel main camera.

Some other details weren’t provided on the slide, but accompany the rumor nonetheless. They say the S III would have LTE and NFC support, retain four hardware Android buttons despite running Ice Cream Sandwich, and be even slimmer than the Galaxy S II. Assuming this information checks out (and some inconsistency in the image suggests it might not), we could be looking at one capable heir to the Galaxy S name.
