It's a nice effort Diomedes,even if you made some miscalculations;at least you're trying to prove your points ;)

The Wii will clearly soon be selling more hardware and software per month than the 360. Look at how close it is with a userbase 1.7million smaller. Just seems so ironic to me.

The 360 has a lot of older games still charting and some of them are $29.99 or even $19.99 in some cases... That's in additional to deals and discounts at various stores. The Wii sells a lot of Nintendo first party games that typically don't see drops in price for a long time (some of the Wii's 1st party launch games are still the same price). There are of course many other variables (a person buying a new system tends to buy games along with it) and the 360 sold the least in January.

Quick look on bestbuy.com (U.S.)

360 
110 games under $49.99
17 of those under $25

PS3
48 games under $49.99
3 of those under $25

Like Legend said, their are a lot of games available for cheap for the 360 compared to the PS3

Make Rockband cost as much as a regular game and it would have sold more! That would be a better value than the Orange Box.

Wii games aren't $60, they're $50 and commonly $40 (games like Zack & Wiki) and $30 (Endless Ocean, RE4) at launch. Assuming they average $50, the Wii would have sold 2,620,000, not 2,183,000 as you calculated (which is assuming $60).

You don't know this given the tiny amount of data you have.  You've made some huge assumptions that immediately break analysis.  At the top: you're using the average cost of a game to calculate how many games sold, but you don't know the average cost per game. 

MS couldn't say, "We made the most sales," because they didn't. MS couldn't say, "we made the most profit," because they never make the most profit. They couldn't even say the meaningless, "we made the most revenue," because they didn't make the most revenue. So they had to say, "In America alone we sold the most money worth of software." Of course, how they calculate their bundled games, Nintendo's bundled game, and Sony's bundled game is up to them.

Microsoft needed to release something that made them look like they weren't falling toward last place fast, which is the reality.

I'm not sure if that's how they calculate those numbers. That would make the whole thing a really inaccurate affair since you have to take into account small stores, stores you don't cover... all sorts of variables.

Most likely they only calculate it by official price cuts by the manufacturer and not individual store cuts and deals.

Of course there is no gurantee the Wii is going to outsell the 360 in software anwyay though the Wii's stats in such a thing are a bit confounding do to it's supply issues and the new market. Never have so many "casual" owners actually bought a system so early in it's life.

The truth is, a lot of these people might end up being like the Atari early adopters. They were "casuals" but the ended up buying a lot of software, a decent amount fell away but ended up buying 8-12 games before they did. So Wii's software arc may be quite unpredictable as the future moves on.

The fact that they pulled out the revenue instead of outright numbers though suggests the Wii might of acually sold more software then the 360 this month.

Since when do we argue with Diomedes?
