@ stever, all the victories in NA between PS3 and 360 were close, and probably within mistake range

What are the PS3 shipped numbers for this quater, or have they not been released?

 We will only know in mid May :(

I agree with Stever89.

So then I'm expecting a million unsold for Ps3 too.

 I still think I'm correct, PS3 and 360 should be about 2x the retail stock of the Wii.

 Anyway, one thing is for sure, PS3 and 360 should be about the same and I kind of agreed with last quarter differences more than this quarter. By the end of 2007 the differences seem more reasonable with the Wii at 800k and both PS3 and 360 at 1.5m.

ioi, please bless us with your wisdom You need to make an official MS analysis 

Don't forget the amount of units in the shipment pipeline. Nintendo likely has more units in the shipment pipeline (shipped, but not yet in stores) than Sony and MS combined, because they're selling more units than Sony and MS combined.

It stands to reason that the faster you sell units, the more will be in your shipment pipeline. So while Nintendo might have 1 million units in a shipment pipeline and nearly zero in stores, Microsoft could have 500k in its shipment pipeline and 500k in stores.

^ the shipment pipeline can be explained pretty well with this thead (the first table I made isn't correct but the one above Sqrls table, and Sqrls table are correct.... though I would prefer you read the whole thread because I was going through a lot of thought processes)

Anyhow, what it proves is that there is a 6 week transition between when Nintendo has a finished Wii (produced consoles) and when that Wii is stated as "shipped" which means that the only shipment pipeline after Nintendo states a console as "shipped" is each retailers own shipping.

I presume hat Nintendo ships them to the US/Europe etc (taking 6 weeks) then perhaps delivers them to the retailers warehouses, at which point they are classed as shipped.
So I doubt there are more than 2-3 days between shipped consoles and on-shelf consoles (unless the retailer wishes to hold them for some reason)

Perhaps when they are averaged out yes, but the shipment numbers are refering to one very small time frame, that being the last day of March.

You know from VGC that the Wii sells roughly 300-400k per week, which means Nintendo have to keep supplying that many each week, what if a big (or just normal will do) shipment of Wii's were counted a couple of days before March 31st, that is an extra 400k on top of whatever supply might have been left in the stores.

MS might have a seperate schedule, they might not have had a shipment go out shortly before April, perhaps holding some for the new quarter and GTA4. they might usually count units shipped on a Wednesday or something (2nd of April) which means that the 19 million figure is 100k+ low, double that if they only ship every 2 weeks (which is possible as MS has no supply problems)

So in that scenario, Nintendo has just "shipped" 400k Wiis which inflates the percieved number on shelves, while MS might not have "shipped" for 1.5 weeks, and were just about to do so in the new quarter.

We really cannot get anything exact from shipment data, because we don't know how each company does it, and when using Wii's massive weekly numbers that might cause discrepancy.

Or even, what about the stores themselves, in the USA there are many places that have been holding Wii's for specific dates which they can advertise and get a line of customers for, they may have been holding onto Wiis which are technically shipped but not on store shelves at any normal time, rather very early in the morning on 1 particular day. 

I agree. That's basically what I was saying (or trying to say), only in a slightly different way, and a little bit added.

Either way, like you said, we can't get solid sales to customers data from it, unless of course we show there's only 100k sitting around for the 360, then we know we overtracked by a bit. But since there's a million on shelves or in shipments, it's hard to say if we're that far off or not.
