So that would mean... "Asteroid Filled w/ Tie Bomber and Tie Pilot"?
Not sure I got that right, but I assumed 'Field' was the correct interpretation given how frequently E's and L's get swapped when people type. Logically I know it probably will just be a sphere as convention dictates. If it is, perhaps I'll have to construct an asteroid fiELd myself.
I also read this as "asteroid FIELD" -- and I'm pretty sure that's what I had read elsewhere too.
A black version of the large two-part planet "sphere" printed with a number of asteroids would be one possibility. The other thing that occurred to me was that they could use a number of the smaller two-part "boulder" pieces (previously used in things in sets like the Power Miners series), supported on transparent stands.
I'm curious to see what Lego actually come up with for this.
On another note, let's hope they also get around to making an updated minifig-scale version of the TIE-bomber in the new black/grey colour scheme. What would be nice would be to include the option to convert the bomber pod to the alternative passenger shuttle pod.
