I say no. And here are my reasons:
1) I like to be completly ignorant of what my city produces.
2) I like to just randomly pick an upgrade without knowing what it will do with the rest of the city.
3) I hate information about anything
4) If they did add this basic feature that just about all 4X games have had for years then it would be a cheap copy and not original.
PS: I was joking. Of Coarse this should be in the game. It should have been in from the get go (no brainer here)
