Whoa whoa whoa! Slow down. Online hasn't even been anounced in Brawl. Online isn't even that big a seller this generation (look at the top selling DS games, most don't have online). Don't assume online, it's just going to dissapoint you if you do.

^^ I´m 95% sure it will have online, will everybody bitch and moan about it, definitly, will everybody use it anyway, definitly, maybe this is something they will show at E3 but my point is that games like smash soccer already have online, you don´t make a good game with online and a mega game without, thats what the vulkan in me is thinking, Smash Brothers was made for online (or was online made for Smash Brothers ???) it would double the replay value for lots of people, eventhough I will enjoy this no matter what I have lots of friends all over the place who I just need to battle and its hard to get them here. OK after reading my own post for errors I´m now 100% sure about online, this is now an official confirmation, I am taking the liberty to speak for Nintendo: Yes Brawl will have online.

Another thing, I really don´t see Galaxy or Brawl to be games for casual gamers, but casual gamers want to try new things too, they will not play Wii sports forever, lots of them will look for something new and they will check out what everyone else is playing, and for me Galaxy is the number one then, Mario games are fun for all ages and not really hard to understand, when my mom got to good at tetris in the 90s she started to play mario on the gameboy and loved it (I had to do the bossfights though). I think it will be the same thing here.  

i think GTA IV will boost sales more for the ps3 than the 360 version just for the simple fact it releases 2 to 3 weeks after halo 3...

We're all imagining that everyone buys lots of games, but a lot of people will only buy a few games those 4 months or so. Meaning Halo 3 and GTA are going to be a lot of people's only purchases on 360.

Especially shooters are going to be hurt by Halo 3, because people will still be enjoying Halo multiplayer and will put off getting other shooters or just decide not to get 'em at all.

Still predict the PS3 to get some timed exclusives this holiday in the shooter department because of this.

ckmlb, I disagree. You coulda said that about Gears of War killing CoD3 and RSV's sales. Don't get me wrong, both did fairly poor @ launch, but RSV is still selling real well, and COD3 managed 1m+ in the US.
