Yeah, at least for now, I see VR as a successful niche market at best. For the reasons you listed, but also because of the cost. Expensive accessories don't often fly well. Maybe once the headsets are totally self-contained they'll have a slightly better shot, but that would only make them more expensive.
Previous comment on the PS4 was based on 25 million world wide sales, according to latest releases that is now 30.2 million. Be interesting to see what Black Friday brings, especially now that it's become fairly global over the last few years and Sony have already announced a price drop.
Should be interesting. If I remember right (don't have my spreadsheets on my home computer), this was the Christmas the PS2 set a record - 8.5 million or something like that. The PS3 moved ~2 million in its equivalent Christmas. I expect PS4 to fall somewhere around 4.5 to 5 million for the season, but Black Friday can be unpredictable.
