Will my Yu-Gi-Oh cards be worth some money in 10 years?

I have a lot of rare Yu-Gi-Oh cards, mint condition, and I have been keeping them for a while now, I know the card gaming business isn't doing that good right now, which kinda gives me the feeling that Yu-Gi-Oh cards will go out of print in a couple years, will they ever be rare in a few years, will collectors want them? Again, I know the card gaming business is not good right now, but how much longer do you think Yu-Gi-Oh cards will last?
