Platinum Games dev retweets info about Nintendo's E3 2015 plans

Could we end up seeing another Nintendo exclusive from Platinum at E3 2015? We already know that Platinum is revealing an unannounced project at E3 via IGN, but we don't have any idea what it is. Thankfully we have some hope that the title could end up being for Nintendo platforms. Turns out that Platinum's Yusuke Hashimoto has retweeted Nintendo's official tweet about their E3 plans. Why would a Platinum employee bother retweeting Nintendo's E3 plans unless they had something to show? Of course, it could be DLC for one of their own games, but I guess we won't find out for sure until this time next week!
