Hi. I just post what I know of the software.
In "Digi-came Watch", Junichi Date recommends SilkyPix to avoid
jagged edge problem of E-300. He says it is a very sophisticated
software loaded with many parameters that is capable of making
pictures of different tastes. Without altering any parameters
(except development quality to the highest 99), its RAW development
was the most natural compared to Olympus Studio and Master. If
there is a drawback, it is the lack of vividness for it apparently
avoids breakdown by subdueing color with highly saturated highlight
parts.

(This article has been mentioned already in this forum, but I
re-post it anyway... You can see side-by-side samples of out of
camera results, Olympus Master, Olympus Studio, and SilkyPix. Very
useful. I might try translating if there is some time left during
this weekend.)
The Q&A section of manufacturer's site says release date of English
version is undetermined for now (question number 7).
When downloaded, one can choose to use it either as a free version
or a trial version. As a free version, there is no expiration date,
but the parameters are limited. By entering "trial product key",
software's full potential can be experienced for 14 days. The trial
code is provided in the dialog box when the software is first
loaded, and the user has to choose how he/she wants to use it by
choosing from two buttons below. (In walk-through screen, "as trial
version" button was displayed to the left, and " as a freeware" was
to the right. But since some softwares switch choices, I rather not
say click one on the left/right. I just suspect that "as trial
version" would always appear longer because of number of characters
involved regardless of presence of Japanese font in PC, and go from
there.) The good news is after 14 days, it can still be used as a
free version
