Right. The console just appeared, as for hardware it's 10 classes over PS3. Working in the gaming industry a while back I've picked up alot on how the industry works.
When a new console appears, the first year will have are shit games (mostly ported from the earlier version) that's why you don't see any improvements in graphics. An A title (top game, COD, Assassin's Creed, etc.) takes about 2-3 years to develop, from the concept to the final release. Won't go in the details and the stages.
Another thing, when it comes to console gaming, all breakthroughs and improvements come with optimization, the better use of the limited resources the console has. When people test an alpha or beta game, they use a dev console (it's a pc looking console that costs about 2-3000$ and has a lot more resources than a console), they do this because the game code isn't optimized for a limited console yet. They focus on functionality and graphics at that point, mostly fixing flaws and bugs.
Also, when a new console gets thrown in the market, game devs have no clue how far they can stretch the resources the console has, they start to use the console at it's fullest capacity after they've released about 3-4 A titles on the market and have a hands on experience on what that console can support in regards to optimization.
The conclusion is that you've bought the console too early to benefit from it's capabilities. In about 1-2 years I assure you you'll see a big difference in graphics compared to PS3.
PS: IMHO you've made a good choice getting the PS4 vs Xbox One. It's better overall, the games will be cheaper and the support is better at Sony. Time will tell anyway
