Trust me, If they don't sell out that weekend, they will be discounting it further on Monday.
On a totaly other random note, I think it is cool that almost everything hitting the market is now Unix and open source derived.
The marketer tells me IF they release on Black Friday (which now pretty much covers the weekend too), they'll make just enough to "sell out", trying to create an artificial demand for the product while hitting the main media outlets with the line "We're so popular because we sold out of all of our tablets this weekend, careful Apple!"
Desperate.
