(PHOTO NOT FOR SALE) (Yonhap)|SEOUL, Jan. 13 (Yonhap) - Krafton [259960]'s new "Callisto Protocol," which was released last month at a cost of about 200 billion won over three years, is observed to badly influence its future performance due to sales shortage.Samsung Securities [016360] predicted in a stock report earlier this month, "The company expected cumulative sales of 5 million copies, but considering the current sales ranking, cumulative sales of 2 million copies will not be easy until this year."Korea Investment & Securities also lowered its cumulative sales estimate of the Callisto Protocol from 4 million to 2.1 million on the previous day, and lowered its operating profit estimate for this year from 813 billion won to 629.3 billion won.This is an improved figure compared to last month, and at the beginning of the release, when the problem of insufficient optimization of the PC version was raised, only 20% of the positive evaluation was made.According to Krafton's business report and quarterly report, the company paid about 196 billion won, including 5.4 billion won in 2020, 77 billion won in 2021, and 113.6 billion won from January to September last year, to the US-based subsidiary 'Striking Distance Studio' (SDS), a developer of Callisto Protocol."
