3 facts:

• I own a Xbox 360.
• I own a PS3.
  
• I don't care about Madworld.

I guess now, you know.
(Wii doesn't appeal me. I had "fun" with the Powerglove back in 1989. No need for more.)

Trolling commences.

MadWorld has about as much chance of converting PS360 owners as LBP had of converting Wii owners. Shame, because LBP's awesome, and I'm sure MadWorld will be as well.

So.. you think ps360 owners would buy a wii because of madworld? Ok.

Who said that?

Edit: Oh, the OP did. In which case he's misusing the term 'upstreaming'.

Probably not, but it seems like it will be a great game

Upstram, downstream I don't care. I am a PS360 owner and suddenly began to desire a Wii strongly as soon as I saw the first two seconds of this awesome title. That stomped on my "Let the kids play Nintendo" attitude and made me see the possibilities.

The whole idea of upstreaming is a neat theory, mostly because it explains Nintendo's actions to date very well. You could see the progression mostly in Nintendo EAD's works from Wii Sports and Wii Play to Galaxy and Mario Kart Wii, then on to Animal Crossing (some would argue Animal Crossing to be more casual than Galaxy or Mario Kart Wii, but while Animal Crossing is easier to play, it requires far more time investment), then further upstream to Wii Sports Resort with it's 10 games in 1 and its more advanced input scheme, then onward to the hazy future of Zelda Wii which could be seen as the natural progression from Galaxy and Wii Sports Resort, and Pikmin 3, the progression upward from Animal Crossing

Malstrom does like to have his ideas fit in neat little boxes, which isn't always the case (it doesn't explain stuff like the ultra-simple Wii Music, or the more complex Metroid Prime 3), but if you use his ideas merely as models as opposed to gospel, they generally come out right

The only time i disagreed with him is the idea that Mario and Zelda games should go back to the level of simplicity they had for their original iterations

I own a Wii but I'm not interested in Madworld. But I've only seen a few gameplay vids, don't know too much about the game. I don't know how it would convince ps360 gamers who don't have a wii to go out and buy one. There are alot of great games comin out soon and many people are dropping some of their "Must Haves" because of cost. For example, some people are saying stuff like "I'm not getting Re5 because I'm getting both K2 and SF4" so it's unlikely they'd buy another console for one more game.

I see it more likely that Ps3 owners will buy 360's because it's the cheapest, and 360 owners getting a Ps3 cause of GoWIII, Gran turismo 5 etc

I don't see Madworld, HoTD or The Conduit as upstream games really. Why? Because they are all very simple games really that any soccer mom could easily grasp and play. Mario Kart is more upstream I think than shooter HoTD. And The Conduit only slight more upstream than Mario Kart. It's pure run and gun. Move and shoot - that's it. Madworld a little more than upstream than that but not much. Don't let the over the top macho bravado fool you - these are all still downstream games. Sega is not being stupid or brave - they just realized all those dad's or husbands of WiiFit owners need a game to call all their own too.

So I don't think HD upstream game owners will care about those downstream games. Too simple, poor graphics (comparitively), little to no online (yeah, yeah, I know the Conduit - It's great for a Wii title but still just the nuts and bolts to 360/PS3)

I do think these games will move some of the casual males a little more upstream though.

I also think Nintendo has big plans to slowly bring out more and more upstream games and slowly win core gamers over to Wii and advance their own downstream audience to their mainstay titles (like Zelda).
