No more 5.2's which are part of the Magnum line (3.9, 5.2, 5.9). Even though DC still calls the 4.7 part of that line it really isn't. It's a totally new engine with aluminum alloy heads. In the near future there will be a 5.7 engine as well which is supposed to be the new Hemi.

Couple of major differences:
1. The 5.2 is a pushrod design, the 4.7 is an overhead cam design. Why did Dodge make the change? Any number of reasons...the prime reason was probably tightening emissions standards. The 5.2 would likely have required some substantial changes to the heads and pistons to meet coming emissions requirements. Rather than re-work an existing design, they probably figured it would be more cost effective in the long run to do a new engine. Now with the OHC design, the 4.7 has potentially more applications within the DC line-up: it would be a sweet engine in a luxury car; possible 4 cam/4 valve layouts, etc.
2. 5.2 has a distributor, 4.7 has individual coils on each plug. Why? more precise control of the spark for better emissions and power.
Bottom line: the 4.7 is cleaner and it's a more car-like engine that can be used in more than DC's truck lines.
