I can't see the next generation of consoles being particularly powerful at all, by the time they come out, PCs will have have advanced so much. Though to be fair, one area I think consoles do hold back multiplatform releases, is when it comes to texture resolution. I'm nearly always disappointed by the texture resolution in games.
Though the main problem really is lazy devs, I do think we will see a change with this though with how PC gaming is growing from huge, to ridiculously huge, the major devs will aim to capitalise on it soon enough, digital distribution is where it's at, and EA have recently came to terms with it, as it makes getting PC games out there so much cheaper with much higher profit margins.
PC gaming is great, but as you said (paraphrased) it really could be so much better.
