Pentax Optio S5n

The Pentax Optio S5n is due out any time now, but I have been informed by a local camera shop that will be some time in April.
Does anyone have an independant review on it? There are some on the internet but they all seem to be copied and pasted from one another.
With the omission of a viewfinder does that mean this new camera is more efficient with its battery use?
Also has the picture noise problem of the Optio S4 been solved?
Thanks in advance for any info.
