Older cards may see an increase in value due to them being much rarer versus new ones. But. With all these new cards flooding the market (especially if they're good) the overall price of all card will go lower. I guess the game will be more affordable if you are in to play and more expensive for the collectors. Who knows!
In other CCG like Magic the Gathering, a new expansion usually means that the majority of the older cards get cheaper because 1) the demand for new cards will be high and the older ones will be less demanded and 2) the older cards get sold to pay for the new ones.
The exception are older cards that combos with the new cards.

Older cards may also decrease in price if they will have an anti from these newer cards. Hence will became from meta to not. :D

It makes a lot of sense
