Rumour: Another Sega franchise making a comeback?

Sega rumours are, by far, the most intriguing rumours making the rounds in the video game business these days. Bruce Kelly, editor of Rumor Reporter and all-around famous guy for shedding light on the best rumours in the industry has news of a returning Sega franchise. Alas, he refrains from saying what exactly it could be. Here's his post in its entirety:

Lots of things have been confirmed as of late. More recently, my mentioning of 20GB PS3s no longer being sold. But come this Friday, I’ve got intriguing news on a couple SEGA-related developments… for Wii. Think NiGHTS was the only retro-game by SEGA coming back to life? Think again. Come Friday and find out what could be one of the biggest no-brainers in retuning franchises to Wii.

Let’s just say that DK: Bongo Blast probably won’t be the only Wii game you’ll be shaking beats to this year.

Now, Rumor Reporter is a site I trust. If we're talking credibility, think way higher than all those EGM rumours. This is the site that originally mentioned the rumours regarding Saturn games on the Virtual Console, which I think is still definitely going to happen in the not-too-distant future.

As for this returning franchise ... well, I'm stumped frankly. If it weren't for the "shaking beats" bit, I'd put some solid cash down on either Panzer Dragoon or Toe Jam and Earl. Also, Bruce says it's a "retro" franchise, but then again, he also refers to NiGHTS as retro. What do you guys think?

[Update: Chris Taran says it could be Space Channel 5. That seems to be the closest match in my opinion, too.]
