I've been wondering - after the destruction of the spheres in the Delphic Expanse, would the Battle of Procyon V actually happen? The Xindi attack on Earth was the result of interference in the timeline by the Sphere Builders - they knew that the Federation was going to defeat them, so they set out to prevent it from ever existing by fabricating a clever story that Humanity would destroy the Xindi in the future, thereby motivating the Xindi to take action to protect themselves and destroy Humanity first.
However, in that original timeline where the Federation won at the Battle of Procyon V, there was never any attack on Earth by the Xindi, Enterprise never went into the Expanse, and the sphere network was never destroyed; the Sphere Builders were able to continue transforming the area in preparation for their invasion. With the destruction of the spheres, wouldn't the Sphere Builders have lost their beach-head and be unable to invade in the 26th century? Were they relying on the spheres and the transformed space in order to launch their invasion? It'd be ironic - by meddling with the timeline and trying to ensure their conquest over our galaxy/universe, they ensure they are never able to invade in the first place.
