I think that the ps3 having been such a money sink while bad does make the ps4 more likely to dominate.
If the ps4 has two or three cells it would still be cheap and a likely candidate for most powerful console next time around. Not to mention helping as far as backward compatability is conncerned.
if the ps4 has blu-ray drive it will be faster(hopefully less need for installs because of read speed) and able to read more than 2 layers. at 25 gb per layer even if they only had 4 layers that would be 100gb. I believe the maximum is 8 layers. Once again since they are already manufacturing the tech it should be cheap as well. Once again helps with backward compatability.
Of course they will probably have another DS controller with decent rumble tech and another pseye even better because Sony makes cameras and I'm sure that tech is improving as well.
Since Sony's 1st party is so big if they plan the software correctly they can really be everything for everyone. Most powerful system, tons of hardcore games (Sony America and Japan) as well as casual(Sony Europe).
I say let Microsoft get all the lead they want. Wait until the time is right and launch with a 299$ monster. I doubt if Microsoft will be able to compete. Nintendo on the other hand probably has an ace up their sleeve.
