Can you tell me what makes you think that the "poor" sony who lost billions this gen, will release a "superior" (and expensive) hardware next gen?
People are always generalizing things.
Nintendo makes a low-powered console one gen = NINTENDO MAKES WEAK HARDWARE
Sony makes the most powerful console of ONE gen = Sony will always release powerful hardware
what would be superior hardware for you (next gen)?
a system with 4GB of ram? 8GB of ram?
if that's it then i'm sorry. you are not getting that anytime soon.
...you seriously don't know me or my approach towards consoles, do you?
Sony was always the comany which released the best design, not necessarily the strongest hardware. The original Playstation mopped the floor with its competitors due to affordability combined with relatively good specs and great third-party support, the PS2 was even better in all those areas despite being the weakest of its generation, the PS3, despite its initial problems (akin to those of the PS2, actually - high price tag being the most major one) was the culmination of their efforts. It is only natural to expect progress from them as they were always on-top of their game.
Microsoft went all-out with the XBox and with the 360, their finances are just fine, it's hard NOT to expect the NextBox to be powerful.
Nintendo on the otherhand... I think that they stopped caring for a while after the Gamecube, tried something different, sold a lot of units and now that they have the financial background, they're getting back in the game. The Gamecube was a fiasco, the N64 was... meh. The Gameboy line is what really kept them afloat through this time.
Read up on some console history before you write something silly again.
