If that's the initial sales for a few days then it's probably enough of a start, assuming good word of mouth and more games. Sony is clearly banking of word of mouth up to the holidays building interest with a medium marketing effort.
In this case though I'm going to take the sales estimates with a big pinch of salt, mainly due to a high level of assumptions and a lack of historic data and examples to extrapolate from. In this case the margin of error I feel is too high to make to many guesses ourselves from the data.
I will say I think Sony should have timed things to have Sorcery release just before Christmas, but this time around they clearly wanted to launch before MS so I guess that's that.
I'm amazed some people though a peripheral with limited titles launching in September would sell by the bucket load. This is a release timed to build interest. It's Kinect that's going for the big launch, close to the holidays, in the hope of having front loaded sales. Sony have made it clear publicliy in their statements they are not aiming for that kind of strategy.
Try to be reasonable... its easier than you think...
