I contacted Olympus UK asking about the new LS-5, about middle of July, and was told the LS-5 was being discontinued. I said it had only been released on the website in the last week, they double checked, and said not only was the LS-5 being discontinued, but so to the LS-10 and LS-11.
Now the Sony PCM-M10 may be good, buy I didn't think it was that good.
Maybe Olympus can sort out their communications soon, however the lack of information on the internet regarding the LS-5 suggests to me Olympus UK told me correct information when they told me it was being discontinued.
