UPDATE: Another scan showing the S.H.MonsterArts King Kong and Ultra-Act Ace Killer (right page of the scan below) has also risen. I'm getting very giddy right now! Kong is slated for an April release while the Ultra-Act Ace Killer is slated for May.
UPDATE: MonsterArts Kong's will cost around 5775 Yen (approx. $68.50 USD) and the Ultra-Act Ace Killer will be priced at 4725 Yen (approx. $56.00 USD).
