Both promise a "true Ghost Recon experience," which implies technologically advanced weaponry, squad-based combat and probably a suitcase that is also a bomb. Ghost Recon Predator (that's the PSP game) will offer customizable squad mates and three-player ad-hoc multiplayer, while the more action-oriented Wii title promises two-player co-op with drop-in play (Ubisoft describes it more interestingly as "Co-op Hot Join").
