I don't know if it's been mentioned, but it seems EO4 will have a limited edition "Famitsu DX Pack", featuring:
- A 51.5cm x 72.8cm tapestry, featuring a piece of art from Himukai, Nagasawa and Yamamoto
- 4 clear files featuring character and scenery illustrations (A4 size)
- A mug cup featuring an illustration by Himukai
Add to that a soundtrack with pre-orders. I really hope it makes its way to eBay, because I can't pass up that tapestry or cup.
