The Botani are harder to pin down. If they were made allies at all, its hard to imagine which side they would align with. The closest thing to a friendly Botani I can think of is the Garrison Follower that could help your lumber mill by shooting flowers at trees. Other than that, the Botani are consumed with trying to have nature dominate all of Draenor.
If their bloodlust were somehow sated and they were reduced to "tree people helping trees" I can seem them aligning with the Alliance.
If they keep their bloodlust, I could seem them going the route of the Taunkan Dark Shaman. A more direct, authoritarian route to Druidism. But even then, theres the issues of female representation and just how to make armor and weapons look good on a tree.
I don't really see the Botani ever being playable, maybe having a larger role as far as NPC's go though.
Arakoa are similiar in my opinion. Either they go the route of the corrupted Arakoa, hunchbacked and squatty, or the redeemed, though that has been taken by the Zandalari Balance Druid form now, at least the skeleton. Armor and female representation again present problems.
What this leaves us then, is two new potential allied races for the Horde and nothing for the Alliance. Unless Blizzard did something off the wall, like Horde gets "New Shiny Draenor Races: Saberon and Ogres" and the Alliance gets the "Old Outland Allies: Broken and Ethereals(although this opens a whole other discussion)", I don't really see how it could work.
