Ya, but it isn't Apples to Apples if you have to invent the scenario to make it such. For people who are looking to invest in a next gen system, their only option was the 360. There was certainly a disparity of games at the time, but for next gen, it was the only representative other than a dream of owning one of the future consoles yet to be released.
With the launch of the other systems, the landscape changes, and now the options are more varied. The PS3's launch could have more games even, but the consensus is obviously the 360 and the Wii have much more to offer, given the sales numbers.
Comparing the sales of the consoles out of the gate, by putting them in a bubble and showing sales figures over relative time lines is only so effective, the PS3 has been destroyed by the Wii and the brand as a whole has been humbled by the 360 in large part due to a lack of system selling titles.
To Sony's credit, the fact that it has sold anywhere close to the number of 360 that MS did in it's first year is impressive.... given the market situation. They had competition, and all MS had to compete with was people saving for future consoles, and the previous gen systems.
Long term, I expect the PS3 to be a great value, but there are too many holes in Sony's foot for it to be within the next 12 months or so. Once they can afford to match the price of the 360's offering, it will have a great chance to explode, but by then the Wii will be $150 and steaming toward all of the Playstation's sales records.
...and while this certainly puts the cart before the horse, how will this affect the next generation? Will Sony allow MS to get a year up on everyone again? What will Nintendo do to improve upon the Wii-fad, will it produce a traditional console next run out to build off of as a core product?
Personally I am looking forward to owning a PS3 some day, but it will be when 'gaming' is a much higher marketing bullet point in their pitch, and their TV spots are showing a lot more of the game being advertised, and a lot less of shiny box levitating/exploding/whatever since the games themselves aren't selling the console.
