Nintendo will be the next to release another console they are the only vendor who can.!
PS3 has very cutting edge hw allready and plenty of scope for far more than any other console
360 similar to above not much to improve is there aside from a model with built in HDD, HDMI, HD-DVD or Blu-Ray, a motion sensitive controller perhaps.
Essentially neither PS3 or 360 can be improved without adding unreasonable costs both are multicore( 360=3*cores , PS3=8*cores) running at over 3GHZ, with .5Gbytes of memory.
Nintendos Wii console is essntially an 50% overclocked gamecube running under 1Ghz , It has an innovative motion controller added. Nintendo have allways been Power PC since gamecube so they can easily upgrade to a 3+Ghz PPC and not loose any backward compatibility (unlike sony or MS who both just switched to Power PC ).
Nintendo can choose to throw in an STI Cell or other multicore Power PC chip at 3-4Ghz , add in say .5 to 2Gb of memory and put out a new console tommorow which is over 10* the performance and 10*memory of the Wii and keep the price similar to Xbox or PS3. Neither Sony or MS can do that because they allready have.
With the success of Wii - Nintendo will have enough time and cash to develop a truly-nextgen console which i expect to see within 2 years.
If they dont bring out a new console in that timeframe the PS3 and 360 will have come down in price and surly both will by then have better next-gen games next year. Wii will begin to loose huge market share to the PS3 especially with it's Wii like motion sensitive and Cell enhanced games, once the price difference comes down.
