Maybe you're thinking too logically here and not just seeing it as a 'tease'. I see it as a tease and not a real statement of intent, if you get my drift. It wouldn't be the first time Neil has done this.

My thoughts exactly.

Dunno where people are getting the idea of emulation from...

I'm hype, PSX 2k15 is coming!
As for PSP emulation, couldnt careless, lel.

Would be pretty cool if true. But I'd much rather have a FFVII Crisis Core HD remaster for PS4.

I'm going to throw this out there as well, and although I don't expect people to take it seriously, I do think it's worth keeping in mind: There are now two articles stating that the NX will launch next year with a shipment of around 10 - 12 million units:

Now, I've speculated that the NX could be a hybrid consoles, which has some validity considering some of the rumours we've been hearing over the last year. IF it does indeed play 3DS games then I think it makes sense for Sony to cut Nintendo off at the pass, so to speak. If one of the big draws for the NX is going to be being able to play your 3DS games on the system then offering the same ability to PS4 owners gives Sony leeway to advertise likewise.

The psp store is shutting down so maybe they'll be compatible on vita and ps4. I'm aware many psp titles currently work on vita and I've bought a few of them but it could be widespread support.

And ps1 and ps2 support on ps4.

I truely expect PS now to integrate ps2 and psp games

I don't see why not. Wii U emulates DS titles. PS4 could handle those buggers easy.

To dream...the possible dreeeeeeeeam!

I need a few coasters. I'll take them PS2 discs.
