"A refreshing change to old difficulties"

This line at the bottom of the update gives me hope.

Does this mean a gw rework? Will there be fewer nodes for those of us that easily complete it every day and want less busy work?

Will it be retooled so level 74 people aren't facing off against zetas on node 11?

Or is it something totally different that I would likely not care about?

Ideas? Thoughts? Rumours?
