I don't think it necessarily has to keep up with VS as that will always be a loosing battle. I just think it needs to feature complete in its own way to make it a viable alternative, and I think they are at the point of achieving that.
The only way to win is to redefine the criteria by which your products are measured in a way that your product becomes the superior one and your huge competitor's can't immediately follow. In this case, you'd have to redefine what an IDE is supposed to do by building one that's much better in a significant scenario than VS.
