Well, if that's true then screw those clueless faggots.
I think Cloud has a point... PlayStation has to be about the most uninspired name ever for a game console... it's so practical on one hand, so focused on purpose, yet so bland... never did have a ring to it. Microsoft could've done worse with XBox, it's not the greatest name either but it's not bad except it also underscores the boxiness of the XBox.
Nintendo is in second place for me with Gameboy (cute) and Gamecube (love the cube part) plus obviously there's a consistency in giving their home and portable systems the "Game" part.
And then...
...then there's Sega. Ahhh.
Dammit, they've just always had the BEST names ever.
Genesis, with its biblical, enigmatic touch. Saturn, named after a celestial body. And the Dreamcast, oh! the Dreamcast... that name alone embodies what the DC really stood for:
dreams, the thought of things possible with that wonderful system. OK, so Sega/Mega CD wasn't terribly original but then that was back when superlatives like "mega" worked on the consuming public.
EDIT: one more thing I just realized... maybe sticking with PlayStation isn't just about branding, rather it would suggest downward compatibility. I don't know if the SNES could ever play NES games, but the PS2 plays PS1 games, the Gameboy Advance plays Gameboy Color and Gameboy Pocket games... whereas Sega always came up with new systems that made a fresh start AND gave them new names accordingly. Ever notice that?
One might be tempted to think that the PlayStation Portable won't be terribly groundbreaking in that we might see a lot of PS1 (PS2?) ports/clones on it.
