OFF-TOPIC WARNING
You can have a look at DCS World if you'd like a good and *free* simulator to play around in until E: D goes live

If you're not familiar with it, the base simulator comes with the SU-25 (Russian ground-attack jet), and the publicly available beta that's going on currently also gives free access to the training version of the P-51 Mustang. The other paid modules, such as the A-10, Huey, and Ka-50 all plug into that, & all work together at the same time - you can fly your SU-25, your friend could be in an F-15, somebody else can be flying the Huey, or an A-10, while yet another person is driving a tank, all at the same time in the same multiplayer session.
The systems modelling in the free SU-25 is fairly basic, but I have to warn you it's a proper simulator and *not* an arcade type game like HAWX, for example. The A-10 module, for example, is a (slightly) watered down version of a training aid that was built for Air National Guard A-10 squadrons. All the switches in the real aircraft are modelled in the sim, and most of them work the way they're supposed to. It's great fun though, & the basic DCS World is definitely a good way to exercise the new joystick without spending any money
Anyway, back on topic - as somebody who falls into the Standard Beta bracket, I'd be quite happy if we were also given slightly earlier access to the single-player component before the launch of the full beta. I'm not too fussed about it though, & there's a large part of me that would prefer to wait for the more fully featured beta.
