This would also be interesting as a whole to judge the state of how prevalent digital is.
For example, based off the 14% sales of UK retail of crysis 2, if 60% of all sales were actually digital that would correspond to the PC having around a 29% share of the market and an actual PROFIT share (since digital is a minimum of 3x more profit than retail, the minimum of which is used in the calculation which obviously accounts for the 60% digital of the 29% only) of a whopping 43% meaning it would be a matter of a few % off total profits of two entire platforms.
Based on the retail sales/player numbers of bad company 2 this sounds perfectly reasonable and it'll be interesting to see how this poll pans out.
It's also interesting to note that although the PC does so ridiculously well based on the 60% assumption (which, based on the data, seems a good one), it is still most definitely worth the time to work on console versions too (although PC should be the priority, always). However with regards to tailoring to an individual platform, the ps3 shouldn't be getting much time at all as it only comes in at a measly 23% profit share compared to the PC's 43% and the xbox's 34%.
EDIT: Seems to be pretty much as expected really, maybe even higher with regards to digital.
Quick comparisons of relative share and profit share for PC based on % digital:
50% digital: sales: 25% profit share: 39%
60% digital: sales: 29% profit share: 43%
70% digital: sales: 35% profit share: 56%
Note how much the profit share inflates due to digitals influence at it's minimum value. If digital accounts for 4x more profit instead (which, i think for steam it does and it definitely will for EADM since all the money goes straight to EA/crytek) the profit share at 60% launches to a 53% instead!
