Greed? Yeah, that's for sure...
But as I said before, to release something for one or two games machines and not others, that, to me, sounds a lot like discrimination, and there are laws against that... I know some high up barristers, I suppose I could get some legal advise, and maybe get them to send EA a Letter... but that sort of stuff costs a large sum of money, barristers are about €1000 per letter. So I've got to be sure that they have broken some law; Unfair Trades Act, Discrimination, or some other such thing...
sadly they can do what they want. It sucks but nothing can be done.
