Here are some of the games I have heard of:

 1. Killer Instinct 3:

Rare has been working on 2 secret games for quite some time, I would assume that this is one.  KI 2 was probably one of my favorite fighting games as a kid so I would be looking forward to this.

 2. Mech Assault 3:

Didnt like the first two but none the less this is to be in development.

3. Jade Empire 2:

The first one was great I thought.  I found it to be short even if you do the side quests but none the less a great game.  Seeing the BioWare is probably busy with ME2, I wonder if this is still on the plate.

4.KOTOR 3:

Probably a top 3 game for the orginal xbox again, I find it hard to believe that BioWare is doing this in addition to ME2 and JE2 (If it is in development).

5. GoldenEye

A classic and in my opinion defined FPS's.  This has been rumored for quite some time so I wouldnt be surprised if it came to XBLA.

6. Spore

Big PC release this year and has been hinted as to coming to the 360.  I am probably getting it for the PC anayways but it should be in here.

 7. Crysis

Already confirmed?  I havent heard much about this but again wouldnt be surprised as MS published it.

8. Diablo 3

Far feched and I would only buy it for the PC anyways but it has been rumored.

Anyone heard anything else that may be coming to the 360?

You should probably specify somewhere besides the very end of your post that you're specifically talking about the 360...

Another 360 wankfest thread huh? Well probaly halo 4, 5 ,6. Probaly gears of war 1.5, the complete version. Probaly another half-ass shooter port from the pc. Dont get me wrong i love my 360 but why can only epic games come to the 360?

"You should probably specify somewhere besides the very end of your post that you're specifically talking about the 360..."

It is in the 360 section of the forums you no

There are some games due out this year that we still don't know much about, Capcom's Dark Void being a good example.

Umm...He posted it in the MS forums if I'm not mistaken, Twestern....That should be enough reason there.

That's a fair point but a lot of ppl like me don't even check the separate forums.  We just go through the "Hot Topics" section on the main page. 

 Exactly, I rarely pay attention to what forum a topic is in and only go to specific forums if I'm making a topic or looking for a specific thread not on the front page.

So yeah, don't be surprised or angry when people come in here giving you their most wanted PS3 and Wii games. 

And I thought I was lazy.

Also, it says at the top of the page which section the topic is in.

Fanatical111,

Some of these title (majority), IF they truly exist, may be released on 2009 ...
