OPMuk, are doing features on the ps4 leading up to its release, today's feature covers the idea of what we will be taking for granted by this time next year. I am too lazy to post each picture and text so I'll just post the headline and highlight just to get the general jist of the situation.

1. Huge Online Battles. Each Planetside 2 map can have upto 2000 players at once.

2. Complex Physics. PS4 is able to render thousands of tiny objects at once in real time.

3. Social Conectivity. When not playing your game, you can use apps on phones/tablets to keep in touch with people in your groups/clan/club etc.

4. Massive Scale. Using Skyrim (which only focused on one region) of the world, on the ps4, it is possible to play on an entire continent.

5. UItra realistic lighting. ps4 power can achieve true photorealism

6. Intelligent AI. whilst this is an obvious thing to note, it does however promise a great future.

7. Seamless Multiplayer. Basically the evolution of MP, blending the line with MMOs

8. Mega Motion Capture. Using COD:Dog as an example, ps4 games will feature even better MO-CAP than its predecessor.

9. Better Visuals of MO-CAP'd actors. I guess it's pretty much the same as the last one but yeah!

if you want to read what was said about each of them, go here.

I already take number 3 for granted now. Have done so for a long time actually lol

You are a gamer ahead of your time!

Fuck ya!

"8. Mega Motion Capture. Using COD:Dog as an example, ps4 games will feature even better MO-CAP than its predecessor."

LOL

sorry, I couldn't resist

3 and 8/9 simply dont matter.
1 is something already done on PC
and every new console promises 6 - Better AI. And it never delivers.

Better mocap because PS4? No, better mocap because better mocap.

dat POWER! Never understimate the POWER of PlayStation!

I love pre-launch of any PlayStation machine. It's like a God's coming to earth everytime and I love the hype for power.

Of course it delivers.  AI, for the most part, is without a doubt better now.  As RAM increases, so does AI potential.  Of course, it all depends on how far developers are willing to go in terms of AI programming.  Still, generally speaking, AI improves with every generation.  It always puzzles me when people say that it hasn't progressed.  Perhaps we just aren't playing the same games.

@OP:

I don't care very much about point 3, 8 and 9, point 5 matters for me when it improves gameplay, and also the atmosphere, when it's essential for the game (for example in stealth games, but not only them).
The other points, particularly 2, 4 and 6, are very important for me, but I fear most publishers will let developers put important resources in point 4 in very few cases, and even when they'll do it, very often large parts of these massive worlds will be sold separately, as expansions or DLCs.
