I'm sure this was posted somewhere else already... and probably in great detail, but speaking of using old 2E modules, does anyone know where I can get some good info on converting 2E Dragonlance over, since I have seen no mention of it in 5E as of yet?
That depends on what parts you are trying to convert. Some of this was mentioned already, but here is what we already have for official 5e Dragonlance:
1) The PHB gives you stats for the Krynnish dwarf, elf, and gnome subraces, by name.
2) The PHB mentions that draconians are a special version of the dragonborn race, but they haven't yet given us stats for them.
3) The PHB gives you the 5e info on the Dragonlance pantheon.
4) The PHB references Dragonlance material in a couple other places. In particular, there is a passage from a novel about a Qualinesti city, and Tika Waylan is used as an example in the Personality and Background chapter.
5) The DMG also references Dragonlance in at least one place (and according to 5e, Takhisis is officially the name by which Tiamat is known on Krynn).
6) A free download has the Krynnish minotaur race.
We can expect to have a 5e mechanical conversion at some point, as we already were given a first draft mechanical conversion for the Eberron setting, and Dragonlance is probably next in line. The only things that we really need are:
A) Wizard traditions for Wizards of High Sorcery
B) A paladin oath for Knights of Solomnia, and
maybe something for Knights of Takhisis/Neraka
C) Stats for draconians and kender
D)
Maybe some Dragonlance specific magic item or monster conversions
Beyond that, all you need is your AD&D material.
That's what you can expect in a 5e conversion: a minimal crunch update to the new ruleset that doesn't mess with the previous lore. (That's kind of perfect for me, as it's all I really need, though I wouldn't mind new campaign setting presentations.)
