I agree that ventilation is more than likely a cure for this problem, but the material that the tent is made of will have some bearing on how much condensation is formed. Think of the example of how Goretex works...... lets the water vapour out, but not droplets in and it works VERY
well. There are thousands of waterproof coats around made from goretex, as
well as some expedition tents that are designed for very high altitude and light weight camping.
Canvas is the same and will generally 'breathe', whilst not letting the rain droplets in. Some canvas is woven differently and will 'breathe' better than some others.
I have the BW turbo 300 in the 'heavy' canvas. We hardly ever put the fly on (unless its looks like inclement weather), we also keep a window or two 'cracked' open and a little ventilation somewhere around the door. You need to create a little cross ventilation to let the water vapour from your breathing and insensible sweating escape.
We have never had any condensation drip on us at all.A mate of
mine tried two oz-tents and he returned both of them due to the condensation issue (he also knows about ventilation), so it is possible that the design (flatish roof) or materials make it worse than other tents, but I would try to keep things open and get some ventilation in there first and see how you go.
I personally can't stand being in a tent that is tightly closed up at night, no matter how cold it is. In fact the colder it is, the more condensation will form and so you should be more inclined to keep things open in colder weather. If you get cold, get a better sleeping bag.
