I guessed 100-109.99. if I need to choose a number, I'll go with 102mm. As others have said, I expect the pie to stay about the same size (though maybe grow a little, as MS is offering a lower cost entry point), and I will expect XB to do significantly better. Signs also point to a short generation (5-6 years), so that's not conducive to high system sales. Probably the low cost XB will grow the pie by about the same amount that cutting a year off the generation will shrink it.
My guess is that there won't be a PSVR 2. I don't think the first one sold well enough to justify it, and Sony hasn't said much about VR lately. With that said, if they do launch a new VR system, it'll be because their research tells them it'll sell well. So, I'll say that it'll do better than the original PSVR.
