I did 2 runs this morning.. 1 in Act 1 and 1 Act Act 2. Act 1 with 280 MF and Act 2 with 210MF after 5NV.
So far, from the limited run, I notice this:-
1. Getting a lot of +MF stuffs. Nearly 1/3 of my rares where with some +MF. Whats the point since MF is to be phased out. Blizzard should just stop having this afflix.
2. More drops from normal mobs. I had like 6-7 drops from normal mobs.
3. Mostly drops are below ilevel 60. Noticed 2 handers getting big DPS boost..had like 2-3 2 handers 1kDPS.
4. Dropped 2 lagendaries. 1 Act 1 and 1 Act 2. Funny thing was Act 1 dropped a nice 2hxbow 1056DPS with ASI 6% CD49%, OS, 44.8% chance to inflic bleed 6-9k for 5 sec (Major boost from the 100-300 we saw earlier) and chance to root. No main stats though..

. Second lagendary from Act 2, a ilevel60 bracers and guess what......+15%MF and GF. 120str and CC of 3.5%. Lol.....so we still do have "Normal" lagendaries drops ..so not all lagendaries will be OP

5. Blue drops are pretty good ...I had a few 900 1 handers...which I vendored..

Will try later..but I think I used up my lagendaries quota for the day...lol
