The addition of the Ghost is really a nice nod. However, I don’t know if Ady would consider this as I do not think he is including additions outside of OG trilogy now. I think the battle droid easter egg from the sandcrawler in ANH is going to be removed for the HD release too. I would love for the Ghost to be included though if possible.
I hope he leaves it in, it’s a very harmless easter egg imo. If you have never seen the prequels, it’s just another droid head and it’s not drawing any special attention.
