No, just no.. as this has already been stated it won't happen, and Dwarfs? Srsly? XD

They already have a plan for PvP in the mists. An explorable area of PvP. They would not make evil and good sides based on characters that one could create. It has been stated. No dwarf characters because of GW lore. You can look it up. :/

YOu should split this into two answers so that we can vote on them each seperatley.

OK, back on topic, I hate the PvP in Lotro, basically becasue it's almost non-existant,a nd when it is, it's totally one sided. The monster play option starts your evil character out at lvl 60, while any light side character starts at one. There's also know way to have an area with garunteed PvP, as each side behaves like PvE and the only player fighting player occurs when light and dark characters questing happens to put them in the same area at the same time.

OK, and "make dwarves" they already made dwarves, the dwarves have had their turn, and they've already *ahem* expired. To bring them back at all in any large amount of numbers, or in any new developements, bedsides the ones stated in EotN, would be a huge hole in the story, "Yea we told yout eh dwarves were gone, and completely focused an expansion ont their destruction, but they're not really gone, and we just hid soem for 250 years." WTF? Sadly, it just won't work.
