My beef with the merger: There wont be a variety of engines any more. Sure, it really doesnt make much of a difference today, but if everyone is running a Ford engine, who cares?
There isn't a variety of engines to begin with. CCWS is powered by Ford. IRL is powered by Honda.
However, if the united series goes with the 2.65L turbo V8s, then Honda could easily haul out their "old" 2.65L turbo V8 they used to run in CART. It's simply cheaper to run the 2.65L turbo V8s (instead of the IRL's current 3.0L NA engines) since it's easier to adjust the turbo engine for oval/road/street races.
A manufacturer spending war destroyed CART and almost destroyed the IRL. The united series must remain a spec-series or else costs will spiral out of control again and force the smaller teams out.

Its amazing how similar the IRL and NASCAR are and yet NASCAR completely steamrolls the IRL in terms of ratings and overall popularity.
Aside from the fact both series are based on oval racing, there are several reasons why NASCAR is #1 in America.
1. NASCAR has better oval racing. Aside from the restrictor plate races at Daytona and Talledega, NASCAR drivers actually have to lift in the corners. NASCAR stock cars can overtake and separate. The IRL has full-throttle pack racing on the 1.5 - 2.0 mile ovals. IRL cars can't get any separation and can barely overtake during these speedway races (which makes it less exciting than NASCAR).
2. NASCAR has better competition. More NASCAR teams and drivers have a shot at winning. Last year, Andretti-Green Racing (Honda's former IRL factory team) totally dominated the competition (which was boring to watch).
3. NASCAR has almost all of the Cup races on network TV. The IRL TV package is nowhere near as good.
4. NASCAR knows how to promote their drivers and racing. The IRL doesn't.
