These are the current world sales and market share %. Each week that follows on the chart includes the previous four weeks sales averages for the entire world. So basically this sheet is trying to predict what sales will trend like based on the previous four weeks of sales. So IF sales average exactly like the previous four weeks then this sheet will show what the exact sales and market share will be.

Things like holidays; price cuts, and newly released AAA games that move a lot of systems will change this chart quickly. So will supply issues like what is happening with the Wii.

At the current rate of sales the sheet says the Wii will catch the 360 by September 9^th. I know there are some predictions of it happening by July, this will be tuff to do but is possible if production was increased high enough. If the Wii can sell 105,000 in the America and Japan for 5/13’s numbers this sheet will then predict Wii to catch 360 by August 26^th, so things can change. This sheet will show with each weeks sales updates that September 9^th date will move closer and closer but can it get to July?

Are you saying that the PS3 will sell 2 million in 4 months, yeh right, especially with some very good games coming before and at the start of September

No

I am not saying anything, but the last four weeks of sales are!

 As I said, Lair and Heavenly Sword will perk up sales a bit, as will GRAW 2 and RSV (a very small bit) and also the sales will continue to tick over and probably increase with the influx of HDTVs in homes

Actually, he has PS3 selling 1.1 million in four months. 3.28 now, 4.38 in September.

 Should have noticed that, sorry.

 I think this is actually fairly generous.  The trend for PS3 sales has been to decrease monthly -- in 4 months they may literally have sold 400K in the US and less than 150K in Japan.  I doubt the European numbers will be 550K.

Motorstorm, Oblivion, VF5 didn't really move any PS3's so why should Lair or Heavenly Sword? The only thing that will really help the PS3 right now is a $200 price drop.

Cool chart. Would be good to update weekly... A suggestion for the next version, is to include the last 4+ weeks, and also highlight which are actual (or at least semi-accurate guesses), and which are purely speculation based on the previous 4 week trends.

I can update it weekly. I have 3 speedsheets (america,japan,others) that all I have to do is plug in the new weekly sales data into and this sheet will automatically update itself. It can average any number of weeks. 4 is just what I decided on because I thought it represented the current trend better.

I guess I dont understand your highlight which are actual ( or at least semi-accurate guesses ).

There are no guesses here, there is no personal input.

This is 100% market trend based on previous 4 weeks.
