Price wouldn't have to be that high.
Current prices on lineup are:
15" $599
17" $999
22" $2499
(remember, the 22" was $3999 when it came out and people still bought them!)
Assume a price drop at MWSF and you get something like:
15" $399
17" $799
22" $1999
That still leave $2K worth of room between the new price on 22" and where the 22" debuted.
I'd guess, based on past experience,
27" $2999
Sweet screen. Too much for me of course, but as they pump out more the prices fall and eventually it will be
99" $999 and I'll be laughing maniacally...
