An interesting question but i doubt we will see higher armours until the current sets are tweaked to peoples liking.
I would like to see higher armours AND higher enemies to balance it out in the next chapter.
This sentence is more reserved for game suggestions but i would like to see magical armours that reduce DoT through absorbtion.
Perhaps purchase special attachments for your armour for poison protection which reduce the DoT from that poison for one time only before it's expended.
The same again for bleeding etc and magical DoT like phantasm.
Armour upgrades would be fun and a great goldsink.
I think the next chapter will have everything (well almost) that people have spoken of on these forums. Anet are fantastic at delivering peoples requests and since the next chapter is a long way off...we can expect a real treat i'm sure.
I've got my brasso ready incase they give us new armour
