Something I never thought about. Kinda long video but he brings some interesting points. BTW ignore the first minute of the video.

Because it's so similar to PC architecture?

(Possibly also a reason why all these used game issues keep popping up)

PS4 will be even harder to hack/emulate than PS3... Sony learned a lot about security this gen.

idk they got ps3 and vita on some serious lockdown. yes its always possible but a really good hack will always make the system accessible to the mass audience like the psp and i dont think sony will allow that

What help the PS3 was the cell. The PS4 doesn't have that advantage.

Usually how far along during a console's life cycle does an emulator develop?

About as easy as the first X-box... which still hasn't a proper emulator. But that's more of a lack of interest than anything.

there isnt even a reliable 360 emulator...

Depends....because the Wii had such a similar architecture to the GC, the Dolphin (the GC and Wii emulator) was updated to play Wii games like 2 years after the Wii release. The PS2 was pretty late in it's life, not 100% sure but the first PS2 emulator was 1 year before the PS3 launch. The DS was also hacked pretty quickly, although I'm not sure when.

On the other hand we had the 360 which has not been emulated yet, but it was able to play hack games since 1 or 2 years after release (but you can't play on Live because MS somehow detects you have a modified console). 

The 3DS hasn't been hack yet, but there are rumors of some hackers that were able to do it (this was just a couple of months ago I believe), so if this is true we could see a way to hack the 3DS maybe this year.

Oh dear. No more E-shop support then.
