GK uploaded the first vlog about PGS7/PGS8: https://youtu.be/bAVVIk61LOo?si=jEYHBiASJ\_Y4\_6Zw. They mentioned (5:40) that DIFX had an issue related to his passport or something similar, and he won’t be arriving for PGS7. It’s also uncertain whether he’ll make it in time for PGS8.
It's a shame—the team, and DIFX in particular, were playing really well, and people were excited to see them at LAN.
