However, in a press release today, the team has announced that they will not be attending. The reason for this is that they have not yet received the 50 000 dollars they won during season 2.
This is the full statement:

It comes with great regret to inform everyone that Begrip CS will not be attending the third season of the WEG. Due to the fact that the prize money for winning Season 2 has not been received, as promised, we have officially declined the opportunity to attend season 3.
We really hope that in the future this sort of thing does not happen at the top level of this environment and the progression of esports globally continues. Our plan is to get the opportunity to attend more WEG events in the future as they grow and develop.
WEG only recently paid out the prize money from season 1, and in a notice they explained that the background was a delay in financial support and tax issues occured by the tourist visas that the players used when travelling to Korea. According to the WEG officials, the latter is the reason why the payout from season 2 is delayed.
No replacement has been chosen as of yet, though an official announcement regarding this is expected soon.
