To be fair, even if they loved IW they would probably say that just to be better received by the old fans.
More like, to be unfair. When you are talking about gameplay concepts, lying just to please old fans would be... idiotic. While Deus Ex almost definitely has a special place in many old gamers' hearts, just kissing up to that crowd would be silly. Especially since it's now been, what, 10 years since DX came out, and it's a PC/PS3/X360 release...
I remembered reading this, and in fact wanted to refer to it a while back, so thanks for digging it up again. While it's nice of them to have a chat with Warren and the Witchboy, I think that having Sheldon Pacotti sign on even to give a vague stamp of approval to the story is a brilliant move. (Now THIS I agree is being done to have the game better received by old fans - not just common sense like distancing yourself from DX:IW)
