I really think this is interesting. I am mum to 1 ds, so have no direct comparison EXCEPT TO MYSELF.
As a little girl I loved playing with cars, had a much better trainset than any of the boys i knew, and a meccano set. As I became a teenager had a minor fling with Sindy (much preferred to Barbie) then discovered clothes and makeup at 14 and became all flirty girl, but to this day with a masculine type interest in cars, and a career ambition which I was told was very male (given up at 39 to care for ds, at least for the time being). My mother has commented that as I grew up I was not as physically affectionate as she expected me to be.
My son (3.5 yrs)loves his cars and trains, does creative things in short bursts (painting, sticking etc) and CAN BE very affectionate, usually when he's tired. He loves playing with his friend's Barbie, but can't stand baby dolls. He is, without doubt, very manipulative, and can throw a tantrum or a thump with the best of them.
Make of it what you like.
