The goal of SC2 should be no more patches and a rotating map pool. I don't know how else to put it - your last idea is flat out bad. If there are continued holes in design perhaps LotV should add new units (Blizz have mentioned that when originally conceived LotV wouldn't necessarily add new multiplayer units), but otherwise trends will develop based on common play styles, and new trends will develop in response. This is evident in BW and even SC2, it's just a lot of the strongest strategies weren't super fun to watch in WoL and I think with HotS that will change.
If you want to play other games, cool. They aren't Starcraft and what makes those other games great isn't necessarily what makes Starcraft great.
I have a feeling this blog is baiting responses based on the sensationalist title, but perhaps this won't fall on deaf ears.
