If it adds any value, in my personal experience, my I-140 had been transferred from TSC to NSC, seemingly for no apparent reason. It eventually got approved at NSC. I eventually discovered that TSC was transferring cases to other service centers to reduce the backlog.
Its seems like your I-485 will get processed at NSC also, and since it got transferred to a service center, and not the local office, at this point, it would not seem like you’ll get an interview, unless NSC transfers it to your local office.
Saras76's case was a bit different where by her unapproved I-140 was transferred to a local office, which outright makes little sense. Kamma's I-485 transfer is different since the I-140 is approved, and seems more akin to a backlog reduction situation, but its not clear whether mvusa's friend is in the exact same situation, unless mvusa can supply the exact case status as shown online.
