Looks like opinions run nearly 50-50 over at the AtariAge thread where this was announced, discussed, debated, argued over, then closed:
Rob Fulop asks for opinions on cart price
In a way, he seems to be still stinging over Cubicolor (a game he released 50 carts for $50 and now goes for $50 buhmazillion dollars each). So he seems to be making sure he gets his fair share of the pie this time. The hardcore Atari collectors at AA seem to be split down the middle between "Gouging profiteer" and "Legendary respected programmer." Thread got ugly.
