Apple only needs to do 3 things with the next ACD:
1. Replace the S-IPS panel with an H-IPS panel (just like what the 24" iMac has). The H-IPS panel is superior to the S-IPS panel in many ways. Too many to list.
2. Add extra ports and HDCP playback. Ports like HDMI and DisplayPort are a must for Apple to remain competitive in the long run.
3. Lower the price (slightly) to stay competitive.
