The bizarre thing is that that many have responded with "no". Considering it purely rationally, even people passionately hating digital would in real life trade a considerably lower value film camera for a M9, if only to sell the latter and buy more/better film gear from the profit.
While it is a valid argument that rare, collectible film Leicas whose current value is on a par with that of a new M9 will predictably grow in value where the M9 will drop (so that swapping would be a poor investment in that particular case), it would be extremely surprising if two out of three participants had nothing but a collectible of that grade as their camera.
