A Shortlist of Potential Engines

After clicking through almost every link of the Wikipedia page "List of Game Engines" (http://en.wikipedia.org/wiki/List_of_game_engines) I've narrowed it down to this short list of new and developing engines:

• PhysX (Nvidias all purpose gaming engine, used in countless games including the recently released Batman: Arkham Asylum game [http://developer.nvidia.com/object/physx.html])
• Havok (or specifically Havok Destruction [http://www.havok.com/index.php?page=havok-destruction])
• Crytek CryEngine 2 (and its editor Sandbox 2). Also CryEngine 3, recently released details show promise [http://www.crytek.com/technology/cryengine-3/specifications/]
• GeoMod 2.0 (Volitions Red Faction: Guerrilla engine which I've already taken a look at. Hopefully more info will be made available in the coming months as they develop new games using it)
  
• id tech 5 (currently under development [http://en.wikipedia.org/wiki/Id_tech_5])
• DX Studio (its physics are handled by PhysX, but it specifies its applications to also include that of architectural visualization [http://www.dxstudio.com/wiki.aspx?n=Applications%20Summary])
• Trinigy Vision Game Engine (also lists itself as software suitable for "serious games" including "architectural walkthroughs". Also has interchangeable middleware for third party software [http://www.trinigy.net/index.php?id=52])
• Itlit RelentENGINE (new engine, where "All Objects React based on Force Exerted and Environmental Resistance", definitely shows potential for structural engineering applications [http://www.itlit.co.za/tech/])
• DICE Frostbite FPS Engine (http://www.dice.se/)
  
• Leadwerks Engine. Perhaps the most interesting of all, working off an accuracy based purely Newtonian physics engine, Newton Game Dynamics (developer not confident/willing to look into structural application due to risks and inaccuracy). Already showing stunning visuals and definetely something to be looked at closer (http://www.leadwerks.com/index.html) and (http://newtondynamics.com/forum/newton.php)
