Now that 360s is in EMEAA how was the launch of the redesign?

[Reasonable]

Good analysis.

In EMEA the new model arrived after the discount so it seems fair to assume the bulk of the spike was the new model.

The only data points I noticed was that in UK the sales of HDD transfer kits spiked massively at a number of retailers and Amazon, right along with the big jump for the 360s, leading me to believe, in addition to other factors, that a lot of the sales may have been to existing 360 owners.

Comparing the new 360 to the new PS3 this makes total sense to me.

The PS3 Slim was a re-design intended to allow for the console to be sold cheaper.  Apart from consuming less power and some tentative suspicions 60 GB models were more prone to failure there was no reason to upgrade a Phat PS3 for a Slim.  In fact, for most people doing so meant downgrading their console.  No doubt some die hard PS3 fans did, but your average PS3 owner wouldn't have been.  As a 60GB BC PS3 owner the Slim has no attraction to me really and I'd be sacrificing features I currently have to buy one.

The 360s though is another story.  It's smaller, quieter, has a smaller power brick, a decent HDD size and built in WiFi.  It is also expected to be far more reliable.  For existing 360 owners the 360s represented a sensible upgrade option.  Particularly in UK most people I know with a 360 or a PS3 use WiFi, and the built in WiFi plus the other features make the new model far more desirable in my book.  If I had an old model 360 I'd seriously consider the upgrade unless my purchase had been made fairly recently.

Of course, another scenario is that potential demand for the 360 was higher than sales have indicated but had been held back by reliability issues plus perceived cost of buying the 360 plus WiFi as an additional cost plus expensive larger HDD.  In which case a fair bit of the spike could be pent up demand for a reliable, more cost effective (for WiFi users and heavy HDD users) 360 console.

If the latter was the case we should see the 360s settle to a much more elevated average weekly sales position.  If the bulk of the sales really were existing owners, then we can expect to see the 360s settle somewhere closer to where the console was before - although I think the new model is good enough to ensure at least a minor average weekly sales rise.

Personally I think it's a split.  The new console (and it's price) doesn't seem enough (unless fear of RROD was massive) to warrant such a jump, particularly in the UK, without a decent price drop so I'm assuming unless proven wrong by the data that a fair chunk of that spike was existing 360 owners buying a 360s, alongside the usual weekly new owners plus a modest spike of additional new owners down to marketing and awareness of the more attractive model.
