Very likely. It would be 13 flavors of awesome to see a map of the current Erfworld, at least the region around GK, to see which sides are closest.
We know Transylvito is close by, but it's forces are mainly intact. If Jetstone is roughly at the same distance, it would make sense to strike them first. Their army was the most heavily depleted and the use of Ansom against them would make the most impact, specially if he's revealed at a crucial moment, say, the battle for Jetstone's capital.
From what we've seen in the last few updates, going after Transylvito might not be such a good idea at the time. They have a number of warlords and presumably a rather large army at their disposal, whilst GK has only Ansom. Even if, and that's a big if, GK had a numeric/strength superiority, their lack of leadership leaves them open to guerilla tactics.
That's GK's main weakness now, the lack of leadership. Sure, Ansom's there, but that's just one warlord while TV has at least half a dozen. Lack of leadership units was not a big issue in the defense of a single city, but if GK intends to expand, they will need more than just one, albeit level 10, warlord.
Stanley may want to expand rapidly, but if Gotti has any input in what comes next, I bet he'll counsel for taking, I'd say, 30 turns to consolidate his forces and build up a reserve. He can have Jack cast a veil to make it look like all of GK became a lava lake if anyone comes snooping around. So while the rest of the world looks for a barbarian Stanley, he can rebuild his dwagon flights, build up on Plaid units (to have a roster of potential warlords) and accumulate funds for rapid unit creation.
Then drop the veil, retake the 2 closest cities promoting units to warlords as they get experience, upgrade those cities to be as defensible as possible, then use them as rally points to take the closest cities, leaving a sizable garrison and a warlord in each of them to defend them in case of a counter assault, as well as to serve as fresh reinforcements.
Now I'm assuming decrypted units can't advance/get experience, so using them for garrison would be strategically sound (except for siege and specialized units such as archons), that way live units get experience, level up and become stronger so even if they do croak the garrisons are made up of strong forces. Although it might be smart to leave a single decrypted archon in each city, for their thinkamancy abilities.
GK can afford a long, slow war. Blitzkrieg style is good for close-range targets and when resources are limited, but since resources are for all purposes unlimited, they can afford to expand, stop, build in and secure their positions, and then expand again.
Whew. All this to say I agree with Maldeus in that we probably won't see all the battles to come. But depending how much time passes between books 1 and 2, we might just have book 2 to begin with the start of GK's expansion. Maybe opening with GK's army marching off to their first battle, the first page being a conversation between Gotti and Sizemore, followed by an impressive 2-page spread of GK's forces leaving the city, countless ground units and flights of dwagons overhead, along with the decrypted archons.
Gentlemen, I like war.
I like trench war, I like Blitzkrieg, I like the offensive, I like the defensive.
I truly love each and every kind of war man can wage on a tabletop game.
