Thinking on this more. Id like to wait a bit for PS3 sales to settle down after initial first weeks on Slim being out. If it settles below 360 then Sony really cant do any more than they have done here.
Interestingly 360 sales are up in America and Europe for last week as you can see on the homepage. I expect 360 to sales to be close to 200,000 WW for this week in next weeks numbers. So it would seem that alot of people are valuing $299 Elite as a good system. Maybe the games library really matters alot to many. I dont know. But since the pricecut of the Elite, 360 sales have improved.
