If you want to... But i really wouldn't care and probably wouldn't even read it.

Because the GBA isn't the Wii. And the audience that was on the GBA, isn't the same as the one that's on the Wii.

I don’t know ... my expectations for Microsoft are a little different.

While Microsoft could go the opposite direction, I think it would make sense for Microsoft to try to encourage developers who are not fully committed to the next generation of systems to treat the XBox 360, the PC, and their next generation system as a single platform. Most games at the moment already have higher detailed graphical assets and more advanced effects being produced for them because they’re being designed for the XBox 360 and being released for the PC as well. If Microsoft convinces developers that they should release all of their XBox 360 games to their next generation system (with higher detailed assets and better graphical effects while running at a better frame-rate at a higher resolution) they could build a library that is made up of the definitive version of most games without requiring developers to fully migrate to their system. The challenge with this is that Microsoft (and a handful of committed developers) would have to produce the content that really drives sales for 12 to 24 months before other developers were willing to make the switch.

X360 will be manufactured and sold 4-4.5 more years.
PS3 6-7 more years.

Wii maybe 4 more years.

The next Xbox will come out in 2.5 years.
PS4 in 3.5 years.

The HD Twins strategy and longevity will be decided by who blinks first.

If MS produce a sucessor to the Xbox 360 next year expect SONY to redouble their efforts and rush PS4 to market.

SONY will not be happy playing catch up to Microsoft again.

I know that a lot of people say the PS3 is future proof but in a sales battle that is meaningless.

All the people on the street will know is that the PS3 is a last gen machine and therefore "OLD TECH".

Nothing sells to the masses like "new and shiny"

no that is how long i think the consoles will last until sales seriously decline(the x360 prediction relies on natal not making it take off, i still think  people will buy a wii over a x360+natal), the next gen consoles should come within the next 2-3 years, but seen as Sony is still trying to make a profit from PS3, they might not bring PS4 until later.

looking at it logically Nintendo will be first after the 3DS launch they'll have a period of at least 18 - 2 years before any new "handheld" could be released and since Nintendos profits are based mainly in hardware we'll see a new Wii being announced at E3 2011

it wont be Wii "HD" but it will probably be a normal Wii with some revision of some sort.

regarding the 360 and PS3 there not budging for a long long time

look at it this year is the "360" relaunch plus Natal 2 is in the works so they've got another 3 years easy left before there sales start to drop.

For Sony they are only just starting to get support and show major potential plus Move so they've got another 3 years yet

not to mention the recession is just ended so money is gonna be tight for a few years so no one will be able to afford a new "flagship" console so they'll be no point in releasing one.

PS4 drops before any other console

I really think that since Nintendo is releasing installments from Mario, Metroid and Zelda either this year or early next year, that it'll be about 2 years before you see a new Nintendo console on the market, as they will likely want to have a strong franchise launch title to accompany it, and historically it's been Mario or Zelda. Of course, this may not be the case as with the enormous success of Mario Kart Wii and the continued strength of Super Smash Bros., either of those franchises could also conceivably launch a new console as well. However, I still believe it'll be a good 2 years before a new console hits, unless Natal and Move do miraculously well. I think you'll see Microsoft look to launch in about 2 years' time as well as it's annual console sales have started to lag, and there's only so much that price cuts can do to stem those losses. Sony I think will hold out a bit longer since they're going to want to try and recoup as much money as they can on the PS3 and won't want to choke off its sales, particularly with the momentum they've built in the last 6-8 months. So Sony is kind of hard to peg down, but I'd guess probably 3 years from now is when they'll launch. Of course, I'm no rocket scientist, and I'm kinda new to following the industry (just always enjoyed playing the games!), but I think those estimates seem reasonable...

People bought the PS2 in greater numbers than the PS3, its hardly a good comparison. For about the first couple of years, most of the good things about the PS3 were the PS2 games you could play and the PS3 didn't have much in the way of compelling game content on its own.

Oh and its doubtful that they would sell the Wii for $100, they wouldn't have the margins to jusify it. The most likely scenario is $150 vs $250.

ps3 and 360 will most likely release new consoles by 2012 , some news leaks will be released sometime in 2011 and boxes shipped in november of 2012.

nintendo on the other hand is very hard to predict it is still selling very well , but most likely around the same time as the others.

i really hope ps4 and xbox "?" push the hardware quite a bit more, 512 mb of ram is just sad at this point in time. even if the systems cost like 600-800 bucks i dont care , i wanna see crazy amounts of draw distance , full 1080p or higher , full high rez textures and all the goodies at 60fps at least.

oh and i wanna see way more online rpg stuff and way way less shooters
