I did not say that PS3 has NO games, but its safe to say that 360 offer a wider range as it is now.
But, most importantly, the entry point to play these games is the hardware price.
If people want to play for example, games like Madden and GTA, then they can look at the price.

So it will cost either 199 dollars to play Madden and/or GTA or it will cost 399 dollars to play the same games. Which entry price to play these games are more appealling?

The other issue you mentioned, multiplatform games.,
Once again, my example I used above. If users want to play the upcoming multiplatgames but DO NOT have a hardware to play them with, which is more appealing to buy? The same games but for less money due to cheaper hardware.

Finally, I do not want to start a list wars of games because its all about personal preference. Both PS3 and 360 will have stellar lineup for this holiday but only one of these machine will have stellar entrypoint regarding price.

I depends on what you think is valuable.

yes, the Ps3 packs in more hardware but what is hardware without games?
What does it matter that the PS3 has all these extra hardware features if I would like to play, let us say, JRPGs? So I want to play games like Blue Dragon, IU, Star Ocean etc.. how will built in wifi and blu ray help me with this?

You are correct in a way, but its about perspective. If you want games, then 360 offers better value. You can buy an Xbox360, with Halo3 and GT4 + 2 other games and still be under the price of a PS3.
I would say that THIS is a better value than the what you wrote.

Well,
Killer Instinct is a Rare IP and thus, it belongs to MS.

EDIT:
Strange, I pressed reply to TechRyzes comment and my post still came on top, huh...

One thing that I feel must happen is that MS should buy the Syndicate IP from EA and let Peter Molyneaux play around with it.

I can easily see stuff like 4 player online co-op, fully destructuble enviroments and perhaps even adding some innovation like "cross platform"-play between PC and 360 in the sense that, the PC guys see the Syndicate game in a "RTS".point of view meanwhile the console-guys see it in 3rd person.

Meaning that both PC and 360 guys play the same game, but they see it differently. The PC guys are basically the "guys sitting in the blimps", giving orders on where to go, and give directives to the guys "on the ground", which are the 360 guys. The orders from the PC-guys can maybe pop up in both text, on the screen on the 360 guys and also with voice ..

Or something like this.

Peter, you know you would like to "re-invent" Syndicate like this. :D
