Are pokemon cards going to be worth a lot in the future?

I have a whole collection, and I'm wondering weather to save them or to sell them now.

Are pokemon cards going to be worth a lot in the future?
I collect pokemon cards and i have the whole set of the very first set to come out. The cards do not go up in value very much. I finished by buying the cards i needed and they were not expensive, many a dollar more than when they came out. Only if you have a very rare card like Charizard Ex from the Fire Red/Leaf Green set. Most cards will not go up in value as they get older. I would sell them now.
Reply:they will stay the same because pokemon cards so poppyler they fallow the same time in the time span but chapion decks and lugia ex and charizard ex will wurth a looooooooooooooooooot of monney.
Reply:yes because they will come out with holograms of pokemon and people wont use the cards anymore. and some nerd will collect them.
