CSTom, Administrator for Master Replicas posted the following on their Ghostbusters Forum:
As a fan, I wish I could reassure everyone that GB is still on for MR. Unfortunately, it is with deep regret that MR has decided to cancel the plans we had with Sony for Ghostbusters. While I cannot get into specifics, I can tell you on a personal level that we cannot afford to give Ghostbusters prop replicas the justice and treatment they deserve and I apologize for any frustration or disappointment this will cause any fans. Rather than hold on to the license and wait for what seemed inevitable, we've decided to make the announcement today. Thank you for your understanding.
He followed up the cancellation post with the following reasons:
I apologize, but honestly I made this post right after a meeting regarding the move. Here's a play by play:
Wednesday - Thursday 02/11 - 02/12: Received incredible prototype of Ghost Trap, took photos and prepped for posting images on Friday. GB still on, seemed to be moving forward.
Friday 02/13: Received e-mail to remove all GB related content with further explanation 02/17.
Today: Found out we're not doing GB anymore. Received approval to notify community.
Sometimes, especially in these times, decisions are unfortunately made very quickly without much of an explanation. If I could have made an announcement sooner, I would have. Up until last Friday, GB was still green lit and excitement and expectations were high. I know it's disappointing, this is not the direction any of us wanted to go in, but it was/is vital.
The only thing that remains is the Ghostbusters Forum on Master Replicas website.
