yeah, the es sounds are *as good as it gets* at this point (overall).
its hard to say, really. the home production market has been bombarded with either with the all-in-one-workstation that clears out three months rent, or the low end, mediocre, gets-the-job-done-but-not-all-that-great-products that are relatively cheap but still a bit too pricey to invest in a lower quality product.
i hope this shores up the mid-range level somewhat. a workstation is a bit useless if i have all my sequencing, sampling, recording, and mixing all on my pc- all i need is sounds.
obviously everyone has different needs, but by and large i hope they start moving towards developing that mid range level more. modules are great but the VST has kind of slowed down those sales, although IMHO a hardware rack module has tremendous advantages over a vst instrument (overall- no cpu drain, the use of its internal effects, better overall quality for a workstation type sound source, to name a few).......
