I don't think that is so surprising given the marked rise in gaming promoted to people 30+ over the last decade. Nintendo in particular have done an brilliant job of taking their platforms into older markets. My parent's, in their sixties, both have DS's, share a Wii and play many desktop games (due to my influence, of which I'm very proud). People in to 30-50 age range have also grown up with the growth of the leisure computing industry, they may well have taken up gaming when the were the correct age (the media expects you to be) to start playing, and never put it down. Also with the growing size of the 'the old' in relation to 'the young' the 30+ age range is probably (guessing) a bigger and growing market share, bring the average up.
