Allthough some may say otherwise, I actually agree with you. Sure this is old games, and old hardware, but remeber who Atari really is: Infogrames. They have no one from the Atari we knew, that knows hardware. They are simply a software company with a big name.
So they start with their "roots" and work up.
To truely know how to make Atari hardware, you must experiance it firsthand.
IMHO if "I" were running Atari, I would slowly step up the technology in my "classic" gaming systems untill they were equal to, or better than that of the modern consoles availible at the time. That way I would in effect mature my design and by the time I'm competeing with the big boys again, I know exactly whats up.
On the other hand, Atari could stay permanetly fixed in te classic gaming arena, and constantly compete with Jakks Pacific. That would be pretty sad if you asked me! It's okay to be in that market for a little while, while you establish your hardware connections, but once you've succeded at that, you need to rise above the nestolgia and go for SUPERSTARDOME!!!!!
