tl;dr
Doctrine changing to make divisions once again the fundamental echelon of maneuver (up from the modular brigade concept). Brigades will still exist, of course, but will fight integrally to their division rather than independently.
Corps level echelon will return to more of a tactical-level combat control.
Five new division TOEs: Armor (Reinforced); Armor; Light; Airborne (JFE); Air Assault (JFE). JFE = Joint Forcible Entry. The "Light" division is the reimagined 'infantry' division, with its combat brigade teams being either or a mix of "light" or "mobile."
Fires (artillery) and recon moved from the brigade to DIV level control. Individual brigades have recon troops (companies), but no longer an integral squadron (battalion).
Divisions will incorporate a 'protection' brigade to C2 ADA, CBRN, MP, and rear area security.
Sustainment elements increased.
Current divisions mapped to one of the new templates, e.g. 1AD, 1CAV, 34 INF(NG) to the Armor(reinforced).
The Armor (reinforced) division indicates x3 armor brigade combat teams (ABCT) and substantial integral engineer/bridging assets. => primary 'penetration' unit.
The Armor (standard) division indicates x2 ABCT + x1 SBCT (Stryker) to provide a more significant infantry and on-road mobility aspect. Less engineer/bridging.
Anyway, that should be enough to whet one's appetite or deter it.
