Let's talk about next-gen, shall we?
Boy, I can't stand reading "next-gen" anymore. But I can't come up with anything better than that.

Probably every GameSpot user saw the repercussions of the Xbox360 launch. To sum it up, not enough consoles to meet the demand, consoles going for $2.000 on eBay, just a handful of games ready for launch, most blockbuster games delayed.
As said by Tor Thorsen (sp?), a rocky launch.

What can we expect for the other two consoles, PS3 and Revolution?

For now, Sony kept the official launch date of the PS3 in spring 2006. Most people, like me, expect it to be delayed, just like Nintendo already did to the Revolution. The reasons are simple: prevent the same rocky launch that we just saw.

There's no word yet if developers got the final devkit. The ones issed by Sony, the last we heard, are 10x slower than the actual hardware on the PS3, since the cell is running at lower clock and it doesn't have the nVidia GPU yet.

I can't see developers finishing their games on this devkit (God, I pray it doesn't happen). Also, in theory, they have less than 4 months to finish their games for the console launch. No word as well on the production status of the consoles, not even if the factories already started working on this.

Now, what about Nintendo? We don't know. No official statements on games, except they are being made, no word on devkits, except that developers can use the GC devkit as a beta, just like Sony's current devkit. But the console is now rumored to launch holiday 2006, one year from now. Maybe they have enough time to sort all the problems MS had with it's launch.
