Longwords and other weapons
I think (but am not sure) that they will be saying that all references to One Handed or Two handed always, without exception, refer to the weapon type, not how its being wielded.
so longsword never, not even in hands of halflings, benefit from anything that says "If you are using a two handed weapon, do extra damage"
Whether that will remain the case, I am not sure.
Another one: Does teleportation count as movement for Intermediate Reaction powers of monsters? I.E. if eladrin teleports next to Orcus, can he be tail-whacked? Since nothing in description of these powers, whether dragon or Orcus, says they count as Opportunity attacks.
