BioWare's upcoming Sonic the Hedgehog RPG may be out in September if US retailers are to be believed.

Listings on the websites of US gaming retail giants (and sister companies) EB Games and GameStop websites show release dates of September 2nd for the mysterious RPG.

At the moment SPOnG would definitely recommend filing this one under 'rumour', however. We contacted SEGA for confirmation but were unsurprised to be met with, "I can't comment on that", by a representative.

Whenever the DS game (which is currently known as Sonic Chronicles: The Dark Brotherhood, although the title has not been confirmed) hits, it will be met with no small amount of interest. BioWare, which was recently bought by Electronic Arts, is one of the West's hottest RPG developers these days. Mass Effect certainly didn't hurt that reputation and SPOnG doesn't expect that working on one of gaming's biggest properties with do it any harm, either.
