Well, maybe you did check out the Lightroom 4 Beta which is downloadable at adobe labs since January. Well, I myself did and I need to say, Adobe did quite a few good improvements. Especially the changes of the development module please me. It is now possible to affect Whites and Blacks directly (well there was a control for blacks before, anyhow) which acts like eg. the levels in Photoshop. With previous versions it wasn't possilbe to adjust the whites individually. The exposure control ist still there. What's missing is fill light and brightness. Instead there are the new controls shadows and highlights, which work quite more like shadows and highlights in Photoshop. It is now possible to e.g. brighten shadows more naturally than it was possible with fill light.
Furthermore the algorithm of the clarity option was enhanced. It now doesn't produce any halos anymore, even at 100%. However, the look of clarity in earlier versions was quite different (more like an unsharp mask with greater radius) and I'd like to be able to achive that look, too. Apart from that, the new clarity control is quite versatile and gives the image some kind of a local contrast boost.
There are further new features in Lightroom 4, but they aren't of that much interest to me. The features that I always missed in Lightroom havent been implemented, as far as I see. That was eg. the option to filter out stacks and the ability to automaticly synchronize folders if one likes to.
