Dang, I forgot about that poster. My favorite part is the dinosaur, haha.
Anyone remember the coupon booklet that NEC sent out? I got one fall of 89, it was packed with coupons for everything. Games, accessories, and systems. Mostly just $5.00 off stuff, but there were tons. I never used any before they expired though (that rental store again). They also sent out another little booklet of the same size that had all the releases they were going to do through the end of 89. It was formatted a lot nicer than the later bi-annual catalogs that they did. That's the only source I have for early release dates (other than my memory of games showing up in stores).
