PS3 was 160k through 2008 in Switzerland according to SIEA and GfK. Haven't seen Austrian numbers for a while, but they were a bit lower than Switzerland, so probably in the region of 100k in Austria. The two countries sold 1m consoles and 9m games between them last year, so they do have a slight significance.
I don't think Austria and Switzerland are included anyway, as along with Benelux they make up the bulk of "Other Europe" sales. It would probably make sense to include them with Germany though, and add one for Benelux. Then throw in Ireland with UK and just rename "Other Europe" as Eastern Europe. Something like:
UK & Ireland
Germany, Switzerland, & Austria (Is there a collective word for these countries?)
France
Iberia
Italy
Benelux
Scandinavia
Eastern Europe
Australia & New Zealand
Rest of the World
It would be a bit clearer at least.
