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.
I’m pretty sure he’s leaving it in. Though I’m not 100% sure.
