These first week sales are almost irrelevant (except that is has sold well). As always, the key will be the staying power of the title. How long will it last in the top-10 - and can it generate sustained sales of the PS3? The PSP also has titles similar to this (sales-wise) when it launched - but not enough titles had staying power. The DS is doing so well because titles are still in the top10/20 1-2 years after release. I haven't seen anything yet that breaks the analogy of the DS vrs PSP & Wii vrs PS3. There is no reason why they shouldn't perform in a similar fashion in the market.
