You actually can kind of.... if you look below the level up message on the bottom left side of the screen you should be able to see the current stats of the city. Sometimes tho this bug's out and displays nothing or unit production, I defiantly agree tho it would be nice if there was a display on the actual message that showed the city's current tech. arcane. and gildar production as well as the bonus's from previous upgrades as well as any boosting buildings present.

Raven is correct on this.

The one issue is that the player might not know which city "Isuuthma" is, given the randomness of names. As the map is uncontrollable at this point of time, a player can easily forget which town is being leveled up, for any number of reasons. Without seeing the details, one is left making a random decision.
