how many steps until a pokemon egg hatches in pokemon platinum?

It all depends on the egg. Some are quick at 2-4,000 steps, others are around 8-10,000 steps.

A good example is Togepi, the first egg you get in Pokemon Platinum, takes about 2,560 steps to hatch while an Eevee Egg takes about 8,960 steps to hatch.

If you're later in the game trying to hatch eggs, it's recommended to have Pokemon with the abilities Magma Armor (Magcargo) or Flame Body (Magmar) next to the eggs to half the number of steps.
