The older models were the same, except that they had questionable 3D from day one (especially the RS45).
Here's my sad tale: I got my first RS40, but it had issues. The convergence was terrible - so bad that a JVC rep commented that it was probably damaged in transit. They were in short supply, so I was told to keep that projector until I could be shipped a replacement. I eventually got a 3D emitter (also in short supply) and the 3D was OK but the dark ghosting had already started to rear its ugly head. When the new RS40 came, I was delighted to see almost no ghosting. Great, I said. Within a couple of hundred hours, that changed. Dark ghosting was back with a vengeance. So, when someone says, "My JVC has almost no ghosting," I say, "Get back to me in a few hundred hours." For me, after 200 hours 3D was really bad. After 300-400 hours it was unwatchable. Add to that the fact that many of the lamps in that early run of JVC's were defective and failed quite early (my second RS40's lamp dimmed to almost nothing overnight, after less than 800 hours).
Now, when 3D on the RS40 was good, it was excellent. But that was because it generated almost no light ghosting (thin light objects against dark backgrounds). Just as with 2D, the JVC's wonderful native contrast made for the best 3D I've ever seen, bar none, in such scenes. But before you could finish "Ooohing and Aaaahing" over how great the 3D was in those scenes, you'd shift to a bright scene. The horrible dark ghosting would rip you out of the 3D movie like a baby from its mother's cozy womb.
I wouldn't recommend that any true 3D lover buy a JVC until they resolve these problems. If you don't care about 3D, by all means get one. It's an incredible 2D projector. As a heavy projector user, and a die hard fan of 3D, JVC is not the projector for me.
