a) in 13 weeks this year, Others sales have gone up/down 15+% in a week 7 times, or more than 50% of the time...another 2 weeks they went up/down 9%

this is in a time with NO major software releases...so supply would be the most likely explanation of the frequent big jumps/dips

3/29 110k (-6%)
3/22 117k (+39%)
3/15 85k  (+4%)
3/08 81k  (-15%)
3/01 96k  (-6%)
2/23 102k (+9%)
2/16 94k  (-30%)
2/09 134k (-9%)
2/02 147k (+27%)
1/26 116k (+3%)
1/19 113k (+72%)
1/12 66k  (-49%)
1/05 130k (-53%)

 compare that to japan, where they see 1-5% each week except around major releases like smash bros...japan seems to be pretty well stocked while others isn't quite there everywhere (tho it may be in many places in others)

b) being available online does not equal having plenty of supply...a good % of customers are only gonna buy their console in a local store...and even of those willing to buy online, most won't know it's available online as they aren't using wiitracker alerts or anything

c) being available in some major stores in some major cities does not equal having plenty of supply...many times the smaller regional shops will be sold out while getting many calls a day for a wii while some of the city stores got a bigger supply so they take a day or two to sell out

d) being available freely in one country does not mean its freely available in some other countries

conclusion: the supply IS getting better in europe, but it is not yet 'freely available' and the numbers ARE affected by the lack of enough consistent supply

It's definitely not constrained here in England and hasn't been for a while.

It's miles better than it used to be, it is now readily avaliable basically everywhere

I think i read an article that since dollar is weaker that most of shipment goes to europe for now instead america. It'll change hopefully.

here finding a Wii is very difficult

Supply constraints is a very vague term, I've never liked it. There are many shades of gray between excess supply and sold out.

At what point does supply constraint occur? Hell if I know.

Definetly not supply constrained here in Ireland. They're readily available at most outlets.

Looking at the graph - start of Jan was supply constrained, the end of Jan/start of Feb was a 'bubble' as supply exceed demand and sales caught up...

End of Feb/March shows no signs of supply constraint - it's fairly flat with a 'bump' at easter/PES08, followed by a tail-off. In other words, the graph looks exactly as it would be expected to look.

-> There is no sign of a significant/meaningful supply constraint in "other".

The majority of Europe is no longer supply constrained, but there are pockets that are, these, however, would not represent major numbers at any rate so flux shoudl be minimal even with these in the tally.

There might be some slight constraint with certain stores selling out at times, but I think it's relatively rare and isolated in Europe. As opposed to NA, where Wiis are whisked off shelves as soon as they're put up.

In case you're wondering why EU might have more variance than the JP market, well, it's a larger and much more complicated market than JP is. So many different nations, so many different economies. It's bound to result is chaotic demand patterns.
