The pilgrim plot only reared its head in the wc movie, and let's face it, the movie is the most disliked product in the franchise.
No way in hell would a new game revive the most unliked wc product. (yeah, I know the movie has some fans here)
It's also pretty cool that in addition to the general timeline integration, Wing Commander Arena (within the game itself) makes a bunch of internal references - the Broadsword was originally introduced as a missile-heavy platform during the Pilgrim War, etc.
*Tentatively raises hand* Along LOAF's lines, I want to point out that the only part of the Kilarthi you really see in the movie is their HEADS. It's not like it's somehow implied that the rest of their bodies are suddenly hairless.
And the Kilrathi in the movie have very cool bodies! Unfortunately the costumes are somewhat stiff when shown on screen, but they have a very menacing posture, that doublejointed ankle-knee, nice claws, etc. They're better than many other appearances where the Kilrathi just have humanoid bodies or a giant robe beneath a lion head.
