I also don't think Sun wants to get into the business of investing in independent game programmers. They are ultimately trying to sell servers and such.
<opinion>Only if they want to go out of business, or get bought out for a pittance next decade, which I'm sure they do not. No large established tech company can ever afford to sit still, and of course the IBM/Sun war over java was started partly because IBM saw "hey, here's a massive industry in it's own right *waiting to be created* that we can create and make money out of, if only Sun would pull their collective thumb out of their arse" and all Sun saw was "yet another programming language which we dont' care much about because we're not a software company".
Sun's behaviour in recent years makes me wonder whether there's an ongoing battle between those who realise this and those who don't. The alternating massive under-investment in java and sudden moves suggest a product being used as a secondary battleground by competing political groups.
Or the first-person shooter that was done after that - Fullscale being the company contracted to do the work. The problem is that they (Sun) have invested in that sort of thing and botched it up by hiding it from the Java
Actually, I tihnk they blew it around the time they decided to get a group of non-games-programmers - worse, academics - to write a game, assuming you meant Full Sail.
