The thing is, if Mr. Spector hadn't been trying to design some a new IP, we would have never gotten any of the System Shocks.
I don't mind a sequel, especially if it's still a good game. But my favourite games tend to be the ones that are something new and awesome, rather than a sequel and awesome.
As you say, you want a new System Shock "in the right hands." But what happens if those hands don't make the game that you want? Do you just dismiss it as "not the right hands after all?"
