PS2 revisions where superficial wheras the advance from GB to GB colour was significant. A slimline handheld will encourage people to re-buy but a slimline PS2 is irrelevant.

I take your point though. 

Its a hardware upgrade if it takes entirely different games. Old giant brick Game Boys played Game Boy Color carts... Right? (The first GB I had was a Color, so I don't know.) But if it did, then it ought to be counted together. Regardless, PS2 is going to cruise past it, and then cruise past 130 million too. People keep underselling the PS2 by saying it will stop at 130 million. Look at how much PS shipped after PS2 launched! I'm thinking 135 million is the over/under, and 140 million is possible. Also of note, the PlayStation line has now shipped 250 million units! 251.27 to be exact. A quarter billion PlayStations since late in 1994! Pretty amazing.

seems fair that the ps2 would be the best selling console of all time seeing as how many great games there were and everything.

its not even $99 yet, then there is 49.99 Ps2 still has a long life in it, freakish long.

PS2 will never hit $50, there's a lower limit to component prices especially when they start making less of them. I don't see PS2 going much below $100. PS2 will probably limp through 2008 but I don't see it selling through 2009 (ie, it will be doing current GameCube numbers).

Gameboy had to sell that many units on a market WAY smaller than the PS2, so try to put that factor in your comparison too.

I think about 2 Billion computers have been sold with roughly a 1.2 billion in use today. http://news.com.com/2100-1040-940713.html but it's a very old artical. It's hard to find any solid numbers that are up to date. this is an interesting site...again it's a little old http://www.pegasus3d.com/total_share.html

not every1 uses their pc as a gaming device (me because my Red Alert 2 broke =[  )

Honestly, is anyone surprised that the PS2 is gonna become the best selling system?
