A few points based on comments above:
1) WWIIOL will probably never be able to compete with AH as a pure flight sim. Heck, the initial release of WWIIOL only has 1940's airplanes: Spit I, 109E, etc. It will be at least a year before you see late-war aircraft. And since AH focuses solely on airplanes, AH will probably always have a better flight model and greater variety of planes than WWIIOL.
2) Regards the money issue: a red herring, if you understand primary school math. If I buy the WWIIOL box for $40 and subscribe for two months, I pay a total of $60. If I subscribe to AH for two months, I pay a total of $60.
3) Someone's sources are going to feel pretty stupid when WWIIOL open beta starts later this month.
