The databank entry on the official site says the new TIE’s are hyperspace capable.
Interesting. That answers that then.
I suppose it could be argued Hyperdrive technology improved similar to how computer chips get tinnier as the years went on in real life.
It’s just a little nitpick thing though. I liked OT Tie Fighters in that it showed how it was different from Rebel ships. Ties are mass produced and disposable (hence its stripped down design that sacrifices the hyperdrive). Alliance ships on the other hand are limited but highly useful and its loss during battles is larger. The ship, like an X Wing, becomes your companion that can take you anywhere.
Then again, times are a little different compared to OT. Each side is more leveled so I’m interested in the direction it takes to add the tension.
