As many people have stated, I doubt there will be a big, noticeable change between version 4/5/6.
Firefox will simply make a slight change and then claim it to be a new version causing thousands more to download the 'newer' version, when deep down all we're doing is downloading the same piece of software.
Despite this, I will be one of those that will jump straight onto the bandwagon and download it.
