While Epic certainly has the ability to make a choice of how they prioritize their obligations, if they had the resources to deliver on their contract with SK and chose an allocation that prevented them from doing so, it gives SK's lawyers the chance to say that Epic drew the contract with SK in bad faith, which is fair more damning than a good faith contract that they failed on.
Bad faith argument would require showing that Epic made promises they knew they couldn't keep.
SK is obviously trying to prove that Epic's intent from day one was a malicious money grab against their licensees. The division and wording of the charges, even in cases where specific behaviors are not necessarily illegal, are all parts of the case that SK is building.
If thats what they are trying to do they will have a very hard time doing it.
It will be hard to convince someone that a Epic with a viable engine licensing business would deliberately torpedo that business to create capital for game development. Where is the malicious money grab when Epic has provided a fully functional 360 engine. SK would have to prove that Epic took their money with no intention of providing the product or the support stipulated in the contract. A six month delay isn't enough to prove that because delays happen even in good faith. Furthermore, the optimized engine for the 360 was provided at the time that Gears was released, so its hard to say its a money grab when the product was available at or before any profits was seen from Gears.
