That's why I included the part in brackets, the more technically inclined buyer (which is basically anyone who isn't a casual gamer) believes (in many cases quite strongly) that the PS3 is a hands down superior package.
Sony are very good at marketing (aka blatant lying) and many people believe this spin and simply refuse to believe otherwise.
For example in Australia in 2008 the consoles standings were:
Xbox 360 - 237,000
PlayStation 3 - 213,000
Which is not a lot, taking into account the price difference (which is larger than the difference in the States)
It shows PS3 sales are growing, despite the high price point.
360 sales largely remained stagnant before the significant price drop gave it a much needed shot of adrenalin.
Non Wii consumers would but the PS3 regardless of price it would seem, while 360 sales seem very much price dependent, especially in territories outside the US where it doesn't enjoy a home field advantage.
You are disregarding that the PS3 had a price drop in Nov '07. This plus the launch of MGS 4 and BR winning the format war all within a few months heavily front-loaded 2008 for the PS3. If you were to compare those numbers for just the first half of 2008 they would probably be in PS3's favor instead of behind. The 360, by comparison, was showing the effects of not having a price drop since Aug '07 (to $450, $350 and $280 for the 3 SKUs) and therefore having already exhausted a larger portion of consumers willing to buy in at that price. The fact that the PS3's monthly sales have been down YOY for the last couple of months seems to be a direct result of comparing post price drop sales to no price drop sales.
Price is *always* a factor.
