Here are some topics they could conceivably cover in such a book:
1. Official mass combat and siege warfare rules (finally!)
2. Variant rules for armor as DR with a class/HD based defense bonus
3. More optional combat maneuvers -- throw, parry, riposte
4. Optional rules for parrying
5. New feat chains, such as feats that make polearms start working the way they should, feats for unarmored swashbuckler type fighters, and feats to use in combat formations (see #1).
6. Rules for the logistics of maintaining an army, supply lines, and morale, including full integration with magic.
7. Prestige classes or feat chains representing different fighting styles ala the PRCs in Swashbuckling Adventures -- cape and sword, berzerker, various dueling school techniques, slinger elite, light cavalry, main gauche and rapier, knife fighting. Note the new classification of PRC types in 3e revised, which now includes utility/special role PRCs.
8. Rules for using vitality/wounds in D&D -- fully integrated with healing magic.
9. Rules for piecemeal armor.
10. Rules variant for weapon and armor deterioration.
11. Rules variant for hit location and called shots.
12. Rules variant to give more advantage to numbers in combat (i.e. ten lower level people can more easily overpower a higher level character)
Who knows? There are tons of subjects that have yet to be covered, not just by WotC but for d20 in general.
I notice that it's complete "warrior" and not complete "fighter," which is some consolation. The title would be pretty confusing if the book were only about fighters and were followed up by books on the other classes. What would they call the other books? The complete roustabout? The complete scout? The complete thaumaturge? The complete holy warrior?
I don't know what this book will be, but I do think that making another book identical in function to Sword and Fist would also be very odd. As a result, I think it will cover new topics. Now, I don't think it will have the focus that I listed above since my preferences and WotC's don't usually coincide, but I suggested the above to show the possibilities that such a book could cover and still be very different from Sword and Fist. It is possible that the book will be a restart of the 2e days and the start of the slippery slope, but who can say at this point?
