Actually Rock, I haven't played a PC game in years. I just think those two games look bloody awesome (And I'd rather play them on a console anyways)

 exactly. This isn't the same Rare as it was in n64 days, and I'm pretty sure it won't be the same Banio.
Of course I'm not saying it's going to be a bad game (although I have a strange feeling there's no reason of getting hyped about this game). Just dont expect same content as it was in original.

BY the way there is going to be a 60GB XBox 360 model soon on the market which will replace the 20GB Pro. MS are working on a XBox 360 which has BLu-Ray drive in it so this will give the PS3 a run for its money. If Blu Ray is what consumers want, MS will deliver. Sony do not hold exclusive rights to Blu-Ray. I guess MS will have to pay to join Blu-Ray association and put Blu-ray in XBox 360.

question. What about games on HD-DVD, how are they going to support that?
360 optic drive will read BR and HD ?

I recommend Lost Odyssey, just got it yesterday and already enjoying it.

gears of war, the trademark game of xbox360, the starting point where 360 started to rise

Lost Odyssey is actually my favorite 360 game.

 The BIG problem with add-ons is: Not everybody has it!

The advantage of owning a PS3 over an xbox360 with bluray for playing movies: NONE that i can think of (still, we'll have to compare qualities once, its out)

The advantage of owning a PS3 over an xbox360 with bluray for playing games: What sort of dumb developper would limit its sales to "just people with a bluray drive" and discourage potential buyers?

Bottomline is: in 4 years from now most games will use most of the capacity of a bluray, there will be a bunch bilayered bluray games (50 GB) and a couple multi-disc games

Just imagine if the original xbox came out with a CD drive and an optional DVD drive that costed you about 150-200 bucks...

They are not giving sony a run for their money.. they are trying to repair a dumb mistake 

Why use multi-disc when you can use a 100GB blu-ray disc instead?

2 reasons:

1: I don't know if all the players accept it..

2: Won't those be rediculously expensive?

but you're right, if these two reasons turn out to be crap, why not?
