Likewise if I had this capability on my PS3, it wouldn't do me any good either. I still need a bigger screen.
Not necessarily a bigger screen, one with superior technology would also do it.
There are any Blu-Ray drives out!? ATAPI?
Yes, there are several models of Blu-Ray drives out, Pioneer is releasing a bare bones OEM PC specific drive soon although they failed to announce pricing as of yet(hoping that it seriously undercuts the free standing Blu-Ray drives available now).
Hmm...never heard that. Interesting nonetheless.
Sony's PS2 Linux site. Them having a Linux PS3 port is a given, it is something they have been actively supporting for years now, nothing new to them.
Got a SM3-supported GF6800
That should be good for about one quarter the power of the PS3's GPU, but you can compensate there with lower resolution at least. You have the feature set.
Well, IMO HL2 and BF2's physics are pretty damn good using the good old CPU.
I don't know about where you live, but where I'm from hand grenades tend to make short work of plywood
HL2's physics I found to be extremely poor at best given the hype. Check out some of the demonstrations Ageia is doing with their PPU- they have ported their SDK over to the PS3 already(XB360 too, but it has to be scaled down considerably) which is a smart move for them as PC processors are so weak they need the PPU to handle the workload and by having the PS3 running titles that require an add in card ports can force users hands to upgrade. The level of physics we are talking about are generations beyond anything we have seen in game to date.
I think it'll be so hard to take advantage of the PPU (break even) that the adoption will come much later than expected.
Except that you have consoles forcing developers hands. PC developers are not going to want to look antiquated when compared to ports from a console- this is what they will be dealing with if they don't implement the technology.
It's not that implementing it is extremely hard, but you're going to need to feed it.
True, but that is coming together significantly faster then anyone could have dared imagine. We already now have one of the most demanding elements of processing spun off on to the SPEs and doing so with power levels far beyond that of the most potent PC processors. And this is an entire SDK- not a one off assembly level tech demo. As of right now it is appearing that the PS3 has superior development tools to the PS2 right now- six years after the release of the PS2 and with some time yet to come for the PS3's release.
Will it also accelerate normal arithmetic (perhaps encoding) providing the software exposes it? Am I just dreaming?
Maybe if they used Cell for their PPUs(not going to happen- way too expensive). The PPU is too dedicated to be used effectively, although it may be possible it can handle some offloading. It won't be able to approach what Cell can do(real time decode of nearly twenty 1080p video streams in real time).
About the consoles: What about custom maps? Game mods? Do current services support any of that? Do future services strive to?
Yes, with hard drives. The PS2, XB, XB360 and PS3 all are capable of expansions and custom maps with hard drives, Game Mod support hasn't been exploited yet in the PC centric way, although they offer games that you can buy that take saves from titles and use that as a launching point. Hmmmm- if you are familiar with Morrowind you can pop in the GoTY edition of the game and use your character from the original Morrowind to go complete the BloodMoon missions that are only available in the GoTY version. It isn't quite like PC games as you don't install titles on the hard drives, although there are ways of doing comparable things. With MMORPGs things work a bit differently, pretty much it works just as the PC versions do(not exactly, but effectively it is the same).
One minus: I heard that next-gen console games (from Activision) will cost $70+.
It will depend on where you shop but don't be surprised to see $59.99 prices as the normal MSRP. This is akin to WoW, HL2 or Doom3 on the PC this generation. Dev costs are going up sharply, although if their is too much consumer backlash(read lack of sales) then they will return the games to their $49.99 price point.
