I actually think the brand hit for MS due to the manufacturing problems was more severe in the UK/EU than it was in any other region, and that stunted the platform's growth. Most people I've talked to that were gamers knew there was problems with the machine (it was reported on the news more than once where I used to live) and it hacked people off that the service took so long for repairs. A lot of that has blown over with the warranty info and the own-up by MS.
I think Oct. and Nov. will be the most telling months for the 360 in the EU/Australia -- September will be an anomaly sales-wise due to Halo, but we should be able to determine whether there's a genuine upswing in sales if both Oct and Nov can continue to build on their momentum. August, too, will be interesting -- it's hard to say what effect Bioshock and the pricecut might have on consumer purchasing.
In terms of big 'Others' software draws, I don't think we'll see any until 2008. 'Huxley' will be fascinating to watch in asian countries, and 'Halo Wars' should do well in the EU.
