As the Vanduul ships are needed for Squadron 42, are we likely to see any bug fixes or updates to the Scythe, the Glaive and the Blade in the near future?

I'm positive we will see updates to those ships. I can't say when.

There's an Easter egg in some of the Nautilus imagery with the Blade that I haven't seen anybody notice.

Even after I heavily suggested it at the talk in Frankfurt, I saw speculation on Spectrum and Reddit as to what it was. And I don't think anyone actually noticed it. I had someone ask me on Twitter if I was just trolling people about it. There are changes. I thought it was going to be totally obvious. I can't not see it whenever I look at the image. I saw someone on Reddit get very close to it and then they were persuaded by other people that it was not that. And there will be similar changes to the Scythe and Glaive. Obviously, they are from an older period. The Vanduul aesthetic has changed at least twice since they were made. So they will be brought in line with the other Vanduul ships.
