KawF is closest. It's fairly obvious that Track7, being a small company with no early support from Sony, rightly decided to make a PC game knowing they could port it fairly easily to the 360 or vice versa.

Now someone's done a feasibility study and discovered it will be too expensive to port the game to the PS3, at least until they've seen some return on their investment in terms of sales for the PC/360.

This is one game cancelled, they've not said they wouldn't be developing for the PS3 in future, especially if Sony could give them some help - like an Alpha dev kit for example.

What it does hint at is an either/or situation, with small publishers having to decide which platform will make them the most money. The safest bet is with the known audience and technology, i.e. PC/360, meaning new games for the PS3 from smaller developers will likely be sparse for quite a while after launch.
