If you've got a really good memory like ours you'll remember Sega promising an Xbox Live Arcade version of the original Sonic the Hedgehog way back at E3 2006. Over a year later and we're finally starting to see the fruit of Sega's XBLA labour.
Alongside Sonic, the latest batch of listings on the ESRB website have also revealed another Sega classic heading for Xbox 360 - Ecco the Dolphin, the old Mega Drive swim-sim that had our younger selves swimming through hoops and bashing whales in the face with our rock-hard dolphin.
Recent rumours of a 'Sega Vintage Collection' for XBLA seem to be rubbish then, but we wouldn't be surprised if more Mega Drive vintage crops up on Microsoft's box sometime soon.
