The PS2 is not part of the current generation, and therefore has no business being compared to this generation's sales.  I've mentioned this in another thread very recently.  The PS2 acheived the majority of it sales during a booming global economy.  Are you in denial of the fact that the Wii is the only console of the current generation to sell 90+ million consoles despite existing in an era of recession?  Anyone can pile up multi-generational stats just for the hell of it and compare them to selected portions of their competition because they feel like it.  Does it serve any purpose?  No.  What is in the forefront of your own statement is that fact that you feel the need to use PS2 sales numbers to prop up the sales numbers of the PS3.  Now, the question is, why do you feel the need to do that?  Is it because Sony went from the #1 market leader of last generation to the last place market holder of this generation?

I can add multi-generational stats too:

Gameboy (118.69 mil) + Gameboy Advance (81.51 mil) + Nintendo DS (152.33 mil) + Wii (96.37 mil) = Nintendo 448.90 million

Play Station (104.25 mil) + Play Station 2 (153.68 mil) + PSP (74.86) + Play Station 3 (65.52 mil) = Sony 398.31 million

See what I just did right there?  3 Nintendo Handhelds and their current console lead the entire Sony console family and their main selling portable by 50 million units.  Now, does my edition serve any other purpose than to show a grouping of Nintendo products housing the same # of Sony products in sales?  Honestly, no it doesn't.  And, that's what I think of not just this specific thread, but of any cross-generational/cross platform argument.  There are variables taking place in other generations that make it senseless to compare them to the one you are currently living in. 

I understand that you don't see the value in this thread, but please don't try derailing it - or if you do have a problem with the information presented, please use more than one word to explain this :)

$30? Where?
