To answer:

1. What if - for fun - and maybe insightful, analysis

2. Of course, X360 won't sell 25 million units - it's basically impossible

3. Attach rate is the only number that you can use for now.  Even with current vgchartz numbers, X360 is generally selling more software in America (main market) on a weekly basis, despite Wii having more consoles sold lifetime.

This indicates to me that:

x360 owners till buy more software on a weekly basis.  Length of time is almost irrelevant in software purchases.

In fact, one can argue that a new Wii buyer should be buying more software than an existing X360 customer.

For example: When a person buys a new XBox, they may buy 1, 2 or 3 games to start with.

When you buy a Wii, if the same pattern hold, then you should buy 1 or 2 games, if you already include sports and play.

So given the Wii's tremendous sales advantage over the 360, shouldn't the Wii sell so much more software based on sheer numbers?

So based on vgchartz numbers, the Wii is not really significantly outsellling the 360 in NA with regards to software, especially if you take out Wii Sports and Wii Play.
Also, note that the numbers are Nintendo's own projections, and their software projections do not include software bundled with hardware.

Nintendo is predicting 177 million Wii software to be sold despite having 46.45 (24.45 + 25) million Wiis total projected sold.  In my what if analysis, X360 will sell 188 million units of software with 45.3 million 360s sold (20.3+25)

1) Nothing wrong with supposing it did.

2) Correct.

3) Consoles with lower hardware sales generally do have high attach rates. Still, the 360 does have an amazing attach ratio for any console.

North America may be the "main" region for software sales, but the bottom line is worldwide sales, which the Wii is doing very well in.

Wii Sports has sold millions in Japan, where it is not bundled. Wii Sports is one of, if the not biggest single reason why the Wii hardware sales so well to so many people. Wii Play is bought by consumers, so that argument is irrelevant. The PS3 and 360 also have bundled software that is included in sales and it's not Nintendo's fault that their bundled software isn't moving hardware like Wii Sports has.

You're stacking the deck for the 360 though. It's simply not a fair comparison in the first place, because it's a scenario that will never exist.

I'm not sure what you mean?

I was just doing a hypothetical situation if Wii and 360 are selling the same amount of hardware.

Does it not make sense?

360 HW price is higher than Wii = higher revenue

360 games revenue is higher than Wii - just on individual unit price alone, even if they sell the exact same amount of software

360 charges for Live , Wii = 0

Wii probably sells more accessories - I am guessing.

So therefore, XBox platform revenue should be higher...

Again, hypothetical scenario....

to continue..

Wiiware games = XBLA games = ?????

XBLive has movies, gamer pics, etc...

So does it not make sense that XBox Platform should be more profitable IF IF IF IF IF
they sell the same amount of hardware?

One can play what if games forever if you discount real the real world, I'm not sure what that accomplishes.

That being said, Nintendo's margins are in the low 20 percentiles. If the 360's margins were anywhere close to that they would have made a heck of a lot more money than they have.

you are talking the impposible.

1. Yes, only for fun.

2. Yes, impossible.

3. Yes, 360 continues to have amazing software sales

4. Yes, worldwide. 

5. Wii Play - I know of several Wii owner who bought Wii Play for the controller.  It's either Wii Play or just a controller.  For $10 bucks - no brainer.

To give you some data from Nintendo:

Wii Consoles sold Japan - FY end Mar 08 - 3.9 million units (LTD = 5.9 million)

Wii Sports sold Japan - FY end Mar 08 - 1.59 million units (can't find LTD numbers)

That's less than 50%.  So for that year, there is about 2 million Wii's sold that didn't buy Wii sports... What are they playing?  Wii fit and other games, but not Wii sports.

So those Nintendo projections probably include Wii Sports in Japan, as it is not bundled.
