if you buy a console for just 1 game and that over a year before release then thats really not sonys problem.
I personally guess that in the next years we will see most big 3rd party games being multiplatform, if you read how much the dev costs for the games on the hd consoles went up compared to last generation then it makes not much sense to release a big game just for one of these consoles.
i heared dev costs doubled from last generation to the hd consoles so you need a lot more sales which you get a lot easier if you go multiplatform. it also doesn't look like any of the hd consoles can really outperform the other saleswise so my prediction for the next years is that more and more 3rd party devs will go multiplatform.
