The recently revealed Samsung Galaxy Alpha has already made quite a splash, but the company likely won't stop there. The stylish metal Alpha is only the beginning of an entire A-series of similar smartphones, according to SamMobile.

The site learned from its "insiders" that Samsung will reveal three other A-series phones in coming weeks: the SM-A300, with a 960x540p display, and the SM-A500 and SM-A700, with Full HD screens.

And lo and behold, a listing for the SM-A500 appears to already be hidden on Samsung's mobile website, though not in any easily digestible format.

So metal

The Samsung Galaxy A-series phones will reportedly all feature designs similar to the Alpha, with metal in their chassis. They'll also have superior front-facing cameras, possibly like the Samsung Galaxy Note 4's rumoured upgraded 3.7-megapixel front snapper.

Since the Note 4 is expected to arrive during IFA 2014, Samsung may debut the three new A-series phones at a later date, so as not to dilute the phablet's spotlight.
