Yes and no, Erin Hunter did mention that she would like to write a super edition on this topic, but it is unlikely that this will be the title of the book. There is currently no planned release date for this book.
Yes, there will be another super edition of Warriors. It will be called SkyClan's Destiny and is set to be released July 21, 2010. There is also going to be another one coming out this year (2011) called Crookedstar's Promise. It sounds interesting!
Yes, there will be a 6th Edition. Rumours say as early as July.
It was going to be called Cruel Seasons but it has been changed to Sunrise

There is currently no sign of that but there is going to be a super edition about SkyClan called SkyClan's Destiny.

They didn't actually just become warriors, the citizens could choose if they wanted to be warriors but when there was a war going on, every citizen that was called to armas had to join the army.
