Adebola,
Usually the 'End-of-sale Date' is contingent on stock levels, meaning they will continue to sell them till Feb 2013 or until stock is depleted, whichever comes first.
As for a replacement display, there are none. Here is the official statement from the EoL notice:
Product Migration Options
There is no replacement available for the Cisco Professional Series LCDs at this time.
Customers are encouraged to select other potential display vendors.
Thanks,
Justin
