With 2.0, FFG will have the ability to tweak the power of basically any card in the game, without compromising the information on our cards. Should an effect, a pilot or a ship be too much or too little, they could change the costs easily.
Aside from typos, unclear wordings, or mistakes (actual errors that the errata is for), there are no strong incentives to modify the text of a card. In fact, one could argue that if you CAN keep the game healthy without changing texts, you should be doing so. That way you can keep your cards relevant for the longest time.
However, I put it to you, this is the wrong way to think about design, and it will lead to similar problems as the tools of 1.0 did.
In some cases, there are effects that are just too powerful or too weak to be balanced by point values alone. Some argue Luke Gunner is one such card. Old Palp had a similar issue according to some. There is simply no indication that such effects will no longer plague the game after 2.0, especially with the ludicrous release schedule FFG alludes to.
Disregarding these problems, and trying to fix them with point values will either result in cards with minimal costs that are still not played, or cards with exorbitant costs that will not be played either.
What I am trying to get across, is that both solutions need to be used simultaneously to achieve a healthy game state. The old X7 was treated right, making the Evade an action, therefore depending on player skill to work, instead of ignoring counterplay options. The decision to change that card's text is the right one, even if we account for the possibility of changing the cost. The mechanic was unfair, and it was made fair, while retaining the cool parts. Similarly, in some cases, raising or decreasing costs is the right way to go, especially when a card does everything the card needs to do, but it is still a sub-par option compared to others.
So, here's hoping that FFG realizes this and will not lock the mechanics of every card in, however useless or powerful they might be, and will use every tool available to them to make the game right.
