The long-awaited announcement has finally come. Sonic Needle Mouse, the code name for Sonic, has been renamed Sonic 4, and will be coming to PSN, Xbox Live Arcade, and WiiWare this summer.

When asked by GameSpot if the Episode 1 meant more Sonic games to come, associate brand manager Ken Balough responded.

“As mentioned, I think the best way to view it is as a first part in a much larger adventure. When Sega released Sonic 3, ultimately it was the part 1 of a story that saw its conclusion in Sonic & Knuckles. In that same spirit, Sonic the Hedgehog 4 is a bigger story, and this is that first chapter. I think it’s also safe to say that by the end of the episode one, fans will be very excited to see what’s in store for episode two!”
