9.1 Legendary Gear

Just got back into the game a few weeks ago. Got a couple classes up to lvl 60 and am getting to the point where I’m close to getting my legendary gear.

With the new patch coming soon. I’m wondering about the item levels and how they will work with the new patch. 235 is the highest ilvl for the legendary at the moment but when the patch comes will buying a 235 even be worth it? Will we be able to make higher ilvl ones or will we have more opportunities to upgrade them again?

I have tried to do a little research but haven’t found much info.
