As long as they don't gave a date, they can't really "disappoint" anybody..

Also that you didn't wait this long for the last version, doesn't mean that you will wait that long for this version..

Did you now that Google Mail was in beta for about 5 years??

I think beta 4 will be the last beta, looking at all the bugs found and reported. I also think that the first month of the final release a lot of small updates will be released (for the "un"-found bugs)
