I've seen similar ones at CES but I'd like to show you my friend Cenk's (GarageGT) driving sim set up. Recaro seat, custom frame and 360 wireless wheel. Still has some stability issues but overall it's a great set up in front of a 150" curtain. A mass market product should have a sturdy frame where you can attach your wheel but where do you store it? Makes me think of those home excersize equipments where you can place them under the couch after you're done. At that point it's up to you if you want to buy a Recaro seat or just use your good ol La-Z-Boy.
