Yeah. The things that are consistent with both are that they're beings with "the Spark" which only a small fraction of sentient beings are born with and an even smaller fraction ever actually awaken, which can be triggered in different ways, like gathering a large amount of power, undergoing extreme mental or physical stress, or having some kind of life changing realization. Once awakened, they gain the ability to "walk" in the Aether between planes and have the potential to wield great power.

One of the biggest differences between them is just how much power. Oldwalkers could draw basically unlimited power from the Aether to achieve pretty much whatever they wanted. They were also naturally immortal and their physical form was just a projection of will.

What caused the change (beyond the fact that they wanted to print Planeswalkers cards and it's really freaking hard to write good stories with immortal, nigh-omnipotent reality jumpers) is that all the power they were siphoning from the Aether was straining reality and ended up causing rifts. A bunch of Planeswalkers sacrificed their sparks to seal them and some other stuff happened and it ended up changing the nature of the spark.

Neowalkers were just mortals with great magical potential and the ability to Planeswalk, which also became harder to do.

There is one Planeswalker that ended up gaining similar power again, though.

Anyway, that was probably more detail than necessary, but I hope I helped some. XD
