Popping up recently on Hideo Kojima's Twitter feed was this image of the Play Arts Kai Meryl Silverburgh figure ... albeit with a nice coat of paint. The color palette looks pretty good, an the paint and sculpt job combo does an OK job of masking some of the figure's joints, I think. No word yet on when to expect Meryl, but it will probably be sometime around the third or fourth quarter of 2012.
Also, you'll find in the gallery pictures of the unpainted Play Arts Kai Solidus Snake, which I believe may have been mentioned but wasn't pictured. The photos are a few weeks old at this point, and also come to us via Kojima's Twitter feed, but it's a great looking figure so far!
