No, it don't work. I've try it.
So far, nothing has been announced, however, in the gaming world, releases can change.
Of course not, that makes as much sense as PS3 games working on a PSOne. Backwards compatability can only do so much. Think about it; if 7800 games would work on your old 2600, why would you need a 7800 in the first place? But in relation to your question, 2600 games are compatible with the 7800 console.
yes SIXAXIS and DUALSHOCK 3 controllers work on any ps3. Any controller that is made for the ps3 will work on any ps3
Yes and the new PS3 move will work on all PS3 models
Yes PS3 games acctually work on ALL PS3's!
No, ps3 controllers do not work with a ps2.
No the ps2 microphones will not work on the ps3
Yes. But, I believe it has to be a next-generation console (Ps3/360).
The next PS3 will just be the 500 GB harddrive PS3 model and in should be out during 2012. The answer is only a theory and is not based on Sony announcements
No PS3 games work on PS3 and Only some other PlayStation games
It does work for the PS3
Yes, they will work anywhere.
