When should the Playstation brand die off?

I think that Killergran has made a good point, going back on topic.  The PlayStation name is more equivalent to the Nintendo name.  

On the other hand, what about that Nintendo name?  Nintendo Entertainment System.  Super Nintendo Entertainment System.  Nintendo Sixty-Foooouuuur 64.  It wasn't until after the third Nintendo system failed to come out on top that they broke with the tradition of integrating the Nintendo name right into the system name.  Gamecube. 

I still think it's unlikely that Sony's next console will be anything other than the PlayStation 4, but ... who knows?  Okama Gamesphere, anyone? 

One major problem here.... Nintendo is the Company name. So Nintendo dropping Nintendo is like Sony dropping Sony from "Sony Playstation"

Basically Playstation is their console name of choice... kinda like how Rex is the Bears quaterback of choice.
