Here are the reasons: to own two guitars, and to play with four people.  In truth, Rock Band is so much better than Guitar Hero it's not even funny; it's like three entirely separate games sandwiched together into an amazing combination platter.

That said, I think it's better if they wait to put out a Wii version if they are able to include online play and (especially) DLC; the PS2 version stripped out both of these features entirely and is far worse for it.  The DLC is a huge feature in Rock Band and the bundle isn't really worthwhile without it due to the unusually large initial investment.

Also, the rock band packs for songs is like 120-180 mb for three songs, while that won't take forever to download, we must remember that the Wii does not have background downloading. You have to watch mario run across the screen for five or ten minutes while your songs download. That would not be fun.

It's more like 75 - 150 MB, but the point still stands. It would be a small price to pay for the option of DLC versus not having the option at all, if a person only owns a Wii and wants the game.

 No DLC is better than no game.

At this point, it isn't like the Wii version is competing with the X360/PS3 versions anyway. The Wii version would be there for those who only have a Wii and still want RB.

That said, EA/Harmonix are missing a lot of money on the table. Activision took a chance and now GH3 is slurping that dough uncontested. 

I think EA lost the opportunity, I rather don't want them to launch, a lot of people already have this game on other consoles, which will point this game to the Wii-only console owners. At that price i don't think they will buy it, and then the "third party on wii is not selling" argument is going to get boosted

I've said this before but I'll say it again for good measure:

The sizes of those downloads is completely unnecessary. The avgerage single song should easily be able to fit under 10 MB including the information about what notes need to be played when etc... I have a feeling they are doing things the hard way and separating each instrument into its own file and mixing it back together at playback.

Whatever the reasons they did it for its not going to change now.

@bulletstopper,

I think all of the "rumors" you mentioned were things that are confirmed to be coming or are simply things that take little thought to realize they are coming. Colors and pricedrops are both things that will come eventually...its not an "if" but a "when". You introduce colors and pricedrops to infuse the product with new interest and as you probably noticed they don't need to do that quite yet. As for DLC in GH3, nobody has ever stated that as confirmed, only that they want to do it.

Where it concerns the sales of GH3, if EA and Harmonix aren't happy with GH3 sales then they need their eyes checked...but I actually think you are completely off-base on this assertion and that the sales of GH3 are the reason they will eventually bring RB to the Wii.

@riot of the blood,

Hmm, it doesn't make sense from your vantage point does it? Its almost like we see things completely differently eh?

@llewdebkram,

Thats kind of funny actually. Seriously I mean it. I've always thought that if GH was put out on the Wii first most gamers would have mocked it for being kiddy and it would have taken a lot longer for it to become popular....luckily the PS2 made it cool first and now we can all enjoy the glory of GH & RB provided we are secure enough in who we are not to be persuaded by insecure naysayers...like yourself.

@topic,

EA & Harmonix are very likely trying to work out with Nintendo how to do an external HD and if/when they do work that out I have a nice phat 320GB hard drive waiting (yes thats right I have spares...both SATA and PATA) to get slapped into that beast and I will have 4x more space than the top of the line PS3 MUAHAHAHAHHAHA!! Even if they try to make it proprietary its no big deal...I know how to solder circuitry ...yet another one of my hobbies that I don't mind throwing a little cash out every now and then =P

i have already made this thread a long time ago.

on the topic:
i am 100 percent sure there will be a wii version of rockband 2.

Honestly, the way the game works, they do need to have separate tracks and mix them during the game.  When you mess up, your specific instrument track doesn't play, but the rest of the tracks continue.  It has an effect in multiplayer, too.  Even with separate tracks, though, they could definitely consume less space than 30-60 MB per song.

@DMeisterJ: Stop trying to impose your own artificial limitations on the Wii.  Again, Smash Bros. appears to have its own download interface that is separate from the Wii Shop Channel, and there is absolutely no reason that Rock Band could not do the same.  Why do you make this stuff up?  Why do you even care, would a fully functional Wii version of Rock Band be some kind of a threat to you?

The Wii can't run Rock Band unless all songs are in midi format

Rock Band is going to the Wii and will probably come out this summer so don't worry.
