IMO, 360 is doing the worst out of all 3 consoles right now.  The Slim effect has completely disintegrated, the once-vaunted Kinect has fallen to ~50k WW and less than Wii Fit Plus, and the upcoming exclusive schedule is very threadbare (except Gears of Wars 3 and the Star Wars Kinect game).  Unlike the Wii, the 360 has been getting a lot of great 3rd party games to keep the momentum going (Dead Space 2, Marvel vs. Capcom 3, Homefront, Crysis 2).  The 360 also has a great entry price of $200 unlike the PS3. 

360 really needs a price-cut to keep hardware moving.  Kinect is not panning out to be the 2nd lifespan of the 360 that MS had hoped.  They threw hundreds of millions in marketing to get a huge initial burst in sales, but they can't afford to keep up that kind of marketing.  Even software sales look to be pretty down for 360.  People are beginning to lose interest in this generation at this price.

kinect needs 500 million advertising campaign again

It's coming, but not until after E3. We'll get a nice slew of games during the holidays, which will be good. Next year should be a whole lot better.

The XBox 360 has diverse games as well. Still has more RPGS then the PS3 which is a bit strange. The XBox 360 has everything. Puzzle, Sports, RTS, (J/W)RPG, FPS, Platform, Fighting 2D & 3D, Driving (lots), Action/Adv, Sims, Casual, Card/Board, Classic and Old School. The system is just as diverse as the PS3.

3DS is not doing as well as I expected. A 70% drop this week, really? What happened to 4 million by the end of March? 3DS sales will boom again when Zelda and Kid Icarus come out, but still. I bet by the end of the month DS and 3DS sales will be similar.

Also I'm really disappointed that no more massive DS titles are comming out. It's life felt too short, but at least it ended with a good Pokemon.

Crysis sales are pretty strong after 3 weeks, and same goes for Halo.

Still no GT5 to be seen in sight, wow it's really selling half the volume of GT4 weekly now...

Looking forward to seeing Michael Jackson sales next week. I wonder if and by how much will the 360 version outsell the PS3 version, and will this be the next hit Kinect title and compete with Wii sales, or will it just be forgotten like Brain and Body Connection.

More RPGS? Debatable. 

Does it have a heavy rain?

A god of war?

An inFAMOUS?

Hell, it doesn't even have an MGS4.

I could go on, but lists wars are meh

It does have multiplats, but thats what they are, multiplats. It does have a diverse library, more diverse than the ps3? No.

4m were shipped units. And it's selling as well as DS was after 3 weeks, so I can't see a problem. As you say, software will drive sales higer, but right now it's doing well.

I don't know.  I'd have to agrue the only one actually doing "horrible" is the 360.  I mean it did have the largest launch for a console perripheral of all time last holiday and its new Slim model, but now it is selling below the PS3 and on par with the Wii.  A console Nintendo hasn't really done much this year to persuade people they want to buy it.  Honestly, I think Nintendo is about to leave this gen behind and is getting ready for the next one, now.  Also this time last year, the PS3 was still coming off the price cut/Slim effect, plus big games like FF13 and GoW3. 

in the end, though, this will mark every console as being on the market for at least 5 years.  You can't expect YOY growth every week/month.  I don't think either of the big 3 are looking for that, either.  They are more happy that they are all selling at a profit and interest in their consoles hasn't dropped to nothing, even in the slowest periods of the year.

Ohhhhh yeah... I forgot that prediction... was before December sales and GT5 sales surprise me a lot.

I wish all my predictions were wrong this way... so the games would sell more of what I hope and I will be happy with that.

I agree with you about PS3 100%. For 360, sales will jump in Fall. 360 might have less games then PS3, but Gears 3 and Forza 4 will generate more hype and sales then all of PS3's exclusives from that time period.

As for Wii, it may be getting a price cut real soon, it's already $170 at Best Buy. So this should boost Wii sales to about PS3 level leaving 360 behind and come fall Wii and 360 should both pick up above PS3. Year end, I still think Wii will come first, but it will be closer this year then any other year in the past.

As for 3DS, when the software comes, sales will jump. It's just annoying Nintendo promised 4 million 3DS's sold by the end of Q1 and I think at best they will get that at the end of May.

I thought DS was a oretty good console. Not as good for the hardcore as the GBA was, but there is a lot more casual software for the DS. I mean I play more Picross then any other handheld game. GB and GBA served the hardcore better with better Pokemon games, better Zeldas, more mainstream Metroid titles, and more new IP's like Advance Wars, Fire Emblem and Golden Sun. However DS had a proper Mario Kart, a couple good Super Mario games, a proper Mario Party, 2 new Pokemons plus a remake, a proper Animal Crossing and a lot of polished $20 titles such as Brain Age and Picross.
