I'm not going to argue with your priorities. I think the SC2 is a solid system, although I don't like their wireless solution because I have personal biases against BT based on my personal experience. Once the SC2 is out in the wild it may prove itself bulletproof. We'll see and I don't pretend to know something they don't know.
So far the SC2 appears to have one killer feature in software. Being able to dial back the force turning the wheel relative to the effects. I hear too often that people turn the their FFB up to uncomfortably high levels just to feel the details. This separation feature allows a way around that. That by itself appears to be a big deal for FFB systems.
Fanatec's software not being complete at release is definitely some egg on their face. I was expecting Fanatec's strong point to be the software, but we still haven't seen what that will eventually be once it's flushed out. I was expecting there to be a period where they cleaned things up.
The SC2 also doesn't requiring cooling in the motor as a relative pro compared to the DD's, but the pro model uses twin power supplies which I consider a negative. I'm sure they have their reasons.
The steering wheel issue is very much a strong pro or a strong con for either system depending on how upscale you want your steering wheels to be. Fanatec has a great selection of less expensive rims and there are some very beautifully designed and executed albeit more expensive wheels for the SC2.
As far as wheel mounts go, the fact that Fanatec already has a change planned for a podium release adds some questions about how that will go and the compability or conversion of their existing wheels.
In the case of an SC2 you can cable your existing wheels or upgrade all your wheels to be wireless. If I at some point went with Fanatec, I could just keep the wheels I have. All 2 of them.
More data points than I had a month ago, not nearly enough to go on. Not remotely itchy to buy, but very curious how this all shakes out. The next few months will be interesting.
For the record I want both systems to thrive. For now I see them aimed at slightly different markets, but definitely as direct competitors.
I was originally thinking Fanatec would come to dominate the market very quickly. Now I think there is more market segmentation than I originally thought and a place for both systems to coexist which is good.
