I will look at Mongoose Traveller...
I will look at Mongoose Traveller, and see what, if anything, we can incorporate into T20. Mongoose is very uneven, and over time, the dollars I spend putting Mongoose product on the game store shelf has declined precipitously. But their Starship Troopers RPG had some interesting ideas, especially regarding military specialization, so I am somewhat optimistic.
As for D&D 4.0, I think WotC currently lacks the talent to improve significantly over 3.5. The inclusion of Mike Mearles makes it slightly less hopeless, but we'll see. If Wizards keeps insulting me with books like their latest piece of tripe, Dungeon Survival Guide, I will be reducing their share of the shelf space even more.
