Im not sure Starcraft can't be revived. Broodwar is the perfect RTS, mostly because it was ingeniously designed fundamentally from the very beginning and then it took another 20 year's of balancing patches as well as a balancing expansion (Broodwar) to turn into the most perfect RTS game, especially in multiplayer, the world has right now. The remaster already put some icing on the cake.
It would be cool if something like Starcraft Broodwar 2 existed, but I don't think it's possible. Or maybe, if they would add one whole new race (which would be ridiculously hard to balance) as well as give all the other races new and upgraded units, in order to even further expand their strategies and ways of play. However, all of this would be super hard to balance out.
I think Phil is just talking about Starcraft's presentation appeal. They could use the universe and make something out of it. World of Starcraft? A remake of Starcraft Ghost? Some sort of team based multiplayer (it would probably be 3rd person). Or just using the IP to make another generic cinematic 3rd person cover shooter-like game.
In any way, I don't think the Starcraft IP will ever see anything truly magical as Starcraft Broodwar ever again, simply because todays AAA game development environment fucking sucks. It's not made by gamers for gamers anymore, that's why it will never be as good.
I'd be hyped for a Starcraft Kart Racing game, though
