ya I definitely think it is possible because they cant be opened, lets see what happens, the voucher system is definitely bad for people who didnt invest or hold sps, and especially new players, but from what Ive read all the previous pack releases were sold out super fast, people know if they buy it out they can flip it later for more, so this is a way to release it slower, so the release can be out for a while, like they did with new reward cards still less than 10% printed. I personally am gonna keep stacking SPS because vouchers will be used even after presale, and also in future releases of content. Thanks for commenting!
