I'm hopeful that any revival would cause a surge in merch for the original. Blu-Rays, maybe a digital distribution deal for the soundtrack albums, print or eBook releases of the canon novels and comics. I'm pretty sure the original Battlestar Galactica had a good amount of stuff come out because the remake was boosting overall interest in the brand. I'm not sure if anything like that happened with the new Lost in Space, but, then, I didn't watch the new one or the original, so it's entirely possible it passed me by.
