Here is my prediction for MWNY. This is not insider information, it is just my own opinion on what Apple will do with thier displays.
A 20" Cinema Display will be introduced for $1499. In addition, the 22" Cinema will have a $500 price cut. The 15" Studio will have a $100 price cut. The result?
15" Studio Display - $499
17" Studio Display - $999
20" Cinema Display - $1499
22" Cinema Display - $1999
Again, this is my prediction. It is not based on any kind of insider info
