that doesn't apply.
Sudden death victory-BRB pg 133;
"If at the end of any game turn, one player has no models on the battlefield his opponent automatically wins."
If using a drop pod assault army, your opponent would have half (rounded up) of his drop pods on the field after the beginning of his half of game-turn one.
Drop Pod Assault-SM codex pg 99;
"At the beginning of your first turn, choose half of your drop pods (rounding up) to make a drop pod assault. Units making a drop pod assault arrive on their controlling player's first turn..."
So even if going second, you will be bringing (at minimum) half your drop pods down. True, your opponent COULD wipe everything that dropped but that would be difficult at best...
