KK did say the Due Diligence will take 6-8 weeks.
If I was Puma, I would take the max time allowed to make sure all looked OK. Heck, I would even ask for an extension!
KK has to remain 'silent' during this period though it should make little difference even if they announced information since the shares have been suspended from trading.
