I believe in Amiga, and now it's getting Amiga OS 4.0, and a new hardware too:
Yeah. Only problem there is that it's been like that for the last 10 years. as long as you have released the original (and can find some proof of it) and have a copy of it in its original form then they cant do anything as you have proof.
Trademark law is about ownership, not proof. You think Microsoft made the worlds first Windows? Of course not. Never the less Lindows is now called Linspire. No legal dept would chance taking legal action against someone where they have a game that pre-dates their claim.
Of course they would. Particularly if they're the only ones who can afford a legal department.To answer your original question, read Oscar Wildes "The Importance of Being Earnest".
