That's what I think, anything new and undiscovered is so because we don't have access to it yet, it would be a shame to make this raid obsolete when it is so awesome and just a higher difficulty wouldn't make sense when there are so many places to put other chests, rewards, bosses etc. like all the hidden caves in the jumping puzzle, the alternate route to the Templar, all the portals working or not there's just so much they can still do and I truly believe we will get more but only when bungie sees fit
