Even though the new coin would be pre-mined to allow for a swap it would only pre-mine the exact number of coins HYPER already has. It is guaranteed that not everyone will swap their HYPER so this would leave an unknown amount of coins left over from the swap that could become the new HYPER Dev Fund to expand HYPER further by providing new gaming sites with some HYPER to add it, similar to what HYPERfuture used to do.

The majority of the coins should make it through the swap process though as places such as Bittrex and DKV hold a large portion of the coins.
