I don't agree on your first point because the current High-level and Expert Dungeons are level synced to level 50. I agree with your second point and disagree with your third but I mentioned the reason why in earlier posts. I just don't think they'll make 4 sets of i130 gear. One from coil, another from sold/carbon, the crafted set, and another set for when you cap to level 60. I'm almost certain the new level 60 tomestone gear will be at least 135 or 140. Really depends on if they want to lower the scale for the new expansion.

The dungeons are not level synced yet, each dungeon has a hidden true level used to determine soulbinding which will likely determine xp gained for completion and kills.

i130 at the end of 2.5X will be equivalent of i70 Darklight at the end of 1.23.

Edit: Seems you misread my post. I do not believe there will be a i130 crafted set that can be equipped at level 50, I believe that the new i130 crafted set introduced in 3.0 will require level 60 to equip.
