ps3 or xbox 360

the new next-gens are coming out and i always buy the the systems. however, i don't buy them all at the same time. a start off with one then i get another then another when i get the money. but i don't know what system to start off with. i know i getting a nintendo revolution when it comes out but i don't know if i should start off with a xbox 360 or should i save up for a PS3.
lets look at the pros and cons.

Xbox 360
--------
Pros* Cons^
-cheap (compared to ps3) -lesser graphics (compared to PS3)
-comes out first -well not as powerful as the PS3
-less lag on live
-DOA 4
-xbox live can still
be better than ps3 online

PS3
---
Pros* Cons^
-better graphics -lots of money ($400-$450)
-more power - bule disc causes longer loading times
-blue disc is hard to program (its what caused the sega
saturn to die) {not the blue disc just hardware that hard to
program for}

hmmm.... well i'm gonna get a xbox 360 first, until i see some PS3 game-play and a real release date and something to back up sony's promises (cuz sony loves to lie)
