It's still hard to see why they did it, but it doesn't seem like it was because of an imminent announcement, and everyone else seems to have lost hope of it being indicative of anything. Price back to where it was, bid back down to 22.5c, depth back to where it was. Very peculiar move from one mysterious buyer! Must have either been impatience or an impulse buy from someone cashed up enough not to care about getting a better price, or someone hoping to create some hype.
