I don't know how "reliable" this source is, but it certainly is a tasty list. Anyone can translate?

What's supposed to be the megaton?

The new console they're releasing. =P

Dolla Dolla,
If this proves true, this would be THE comeback of SEGA many, including myself, have been waiting for!

Seriously, if Shenmue III, not to mention remakes or repacks of I and II hit the 360, look out RROD here I come!

More so a megaton for old Sega fans, as DoesWhatNintenDont pointed out. Shenmue was big in its day, and many enjoyed Jet Set Radio, as well. A lot of old games revived in this, including Fighters Megamix (Virtua Fighter/Fighting Vipers) and Crazy Taxi.

Also, is Sonic RPG the one they are working with Bioware on?

I saw this list posted on other boards and everyone (including me) think its fake.

Shenmue and Jet Set Radio returning?

I won't believe it till I See it.

If I see it I will love it and buy it :D

I think this list is bogus though. The Sonic RPG is for the DS not for the 360 and PS3.

The one thing that I see that I didn't know about and think will happen is Yakuza 3 coming to the PS3.

Edit: That Samba De Amigo game in there if it turns out it's coming to the PSP will definitely find a buyer in me.

As for a megaton announcement there are obviously some Sega franchises missing from that list like Shining Force, Golden Axe, Panzer Dragoon, etc, maybe they'll announce a next generation sequel to one of those?

Doesn't look right. Why would they only bring Shenmue to the 360? Agree with ckmlb about Sonic RPG as well.

This probably sounds crazy but I always wondered why Microsoft didn't simply just buy Sega and branded the Xbox 360 as the Sega 360 in Japan. Just on name alone and having such a well respected developer making games exclusively for the system would have went a long way in helping the 360 in Japan.
