Starblazer Adventures should be out soon and by all accounts should be packed full of sci-fi inspiration, even if the FATE system it uses is too postmodernist for my tastes. It's kinda odd - Starblazer is based on straightforward 1970s sci-fi adventure comics from my childhood, but has established itself pre-release as an rpgnet darling, which has to be at least partly due to using the same ruleset as Spirit of the Century.
Troll Lord's StarSiege: Event Horizon should also be on general release soon and looks like being a clean, simple sf system, d20-based system for easy adaptability.
These are the two I'm waiting for, anyway - though I think I may get Mongoose Traveller too, I've heard a lot of good things about it. Starblazer is aimed at high octane rock & roll space opera, Traveller has a much more 'low sci fi' feel; higher on realism, lower on the blasters and giant space monsters/robots. StarSiege seems to be aimed also primarily at the lower-sf end - more Aliens than Buck Rogers, though the designer says it's intended to be adaptable for various levels, which Traveller really isn't.
