Hi!
Sorry for not reporting it here earlier. I've been browsing these forums too for quite some time, and had a vague memory of having posted something here, but upon trying to log in I realised that was incorrect. Being a bit late (somewhere around two in the night) I didn't quite feel up to starting the registration process right then.
Thank you as22 for getting the message across to here!
My recommendation is to keep your eyes open on that page, because you'll almost always get the information about the latest software updates there first. It does however take a few weeks usually before things are available in english versions. Whether this is because of translation needs or if they are prepared at the same time but simply not published I don't know...
If anyone have tried the Vista driver, whether it's a japanese one or a translated one, it'd be interesting to hear how it works, since I'm currently not on Vista myself.
