555 in Spain..... later octuber... earlier November

Hi This is my first post

Today i contacted with a Internet reseller, and they told me that it was the range when that camera will be available. They have nice prices, but i'm afraid about how much there will it cost, because in some places i've seen the 555 at 720 € and more!!!!

This will be my first digital camera, until now i've been using a small konica z-up 90! Very nice a very accurately camera, but i'm so obsesed with taking pictures (like a japanese tourist) so soon i'll don have space in my house to put all the pictures....

Well.. enough about, since i've seen the reviews i fell interested in the 550, but when read the issues about noise at high ISOs i doubt... My options are:
Wait for the 555, someone can confirm if that model solves the noise issues?

Look for another similar camera, the problem is that there isn't any model that have both: 5MP an 5 optical zoom at that price range.

In a review at: http://www.marksdigitalcameras.com/pentax_optio_555.html you can see this:" Noise reduction function

For longer exposures, the Optio555 automatically activates a function for reduced interference. "

This a NEW feature in the 555 or is only marketing since the 550 already has it (or is it?).

Thanks again and excuse if my english isn't enough good.
