Luke Smith, a news editor at 1UP, had something interesting to say on his blog. After expressing his frustrations of not being able to reveal any news due to NDAs, he dropped a bombshell of an announcement that's seen a flurry of speculation.

"A game you never expected to see as an MMO is about to become one - and it's not coming to the Revolution."

Why did he specifically mention the Revolution? This opens up one of three possibilities.

A. It will be a third-party game that seems Nintendo-y, but will be on PS3, PSP, and/or Xbox 360
If it's this, I'd say Sonic might be a good guess. Sonic games have sold very well on the GCN compared to the PS2 and Xbox, and IIRC there were plans for a Sonic MMO years ago that got scrapped. Or maybe Harvest Moon?

B. It will be a Nintendo Franchise that will be on the DS
If Pokemon becomes an MMORPG, I will actually buy my first Pokemon game since Stadium 2 for the Nintendo 64. However, Pokemon is something people have been asking for as an MMORPG for quite some time... I'd also be a bit disappointed that it wouldn't be done on the Revolution instead. If it's a Zelda MMORPG, I'll probably cry. Zelda needs to stay single-player. A bounty-hunting Metroid one would be interesting, but the character designs in Metroid Prime Hunters left a lot to be desired. A Mario MMO would just be plain whacko...

C. The Revolution comment was to just throw us off or fake altogether
In which case Luke Smith would be a sadistic bastard ;_;

Whatever it is, it'll likely be revealed at E3 and QJ will be there to see for ourselves.
