Over on Reddit, the graphics quality differences between The Sims 3 and the upcoming The Sims 4 have been compared. The resulting image is below; click to see the full size.
While the game should be nearing the final stages of development, there has been no official statement from EA as to whether the graphics displayed in the promotional images will match those in the final product.
The loss of sharpness is easily attributed to EA’s promise that The Sims 4 will have lower system requirements than its predecessor. I personally feel that the TS4 graphics are superior, artistically, to those found in previous games. It’s all a matter of opinion I guess.
