What I view as likely:
-The Slann’s disciplines, rather than being 50 points a piece, will vary on a power by power basis like the Vampire powers and Ogre big names.
-The special characters will get a little more reasonably priced, but that won’t materially affect people’s opinion of them. At least one new finecast SC model will come out.
-Razordon will be able to march and shoot
-We’ll get a new large dinosaur
-Swarms become cheaper, but not cheap enough that people will want to regularly use them
-No magic items costing less than 25 points in the 7th ed book make it to 8th edition
-Carnosaurs become a little cheaper, but not enough to dissuade most people from taking a Slann instead of an Oldblood general.
-The 8th ed LM army book will be one of the last 8th ed books to come out
What I view as possible:
-We will get a new dinosaur that is a Sea Monster
-We will get a dual dinosaur kit with the new dinosaur and a Stegadon or Carnosaur
-Salamanders will become more expensive/less powerful.
-Skink Priests will be able to ride Terradons
-Skink Horned One Cavalry will come back, become potential skink character mounts (not magic items)
-If that is the case, there will be a Saurus Cav/Skink Cav combo box like with Black Knights and Hex Wraiths
-Saurus spears/hand weapons become an option not costing extra points either way.
-Kroxigor in a skink block become more expensive than Kroxigor outside a Skink block to balance out the choice
-LM gain a new left over tech of the Old Ones to join the ranks of the Slann Palanquin and Engine of the Gods
-Temple Guard Shields become an elective option rather than standard issue
-The new monster book I hear about coming out will foreshadow something we get in our army book
-We get plastic Kroxigors
-Slann regain the ability to choose spells from multiple lores like in sixth edition
-Saurus get two hand weapon options
What I view as possible but unlikely:
-We will get a Kroxigor hero
-We will get a coatl
-Skroxigor will be removed from the list, Kroxigor get some kind of very weak synergy bonus with Skinks like before.
-Marks of the Old Ones come back
-Chameleon Skinks become Rare
-We will get a new unit that isn’t strictly reptilian, Slave Warriors of the City of Moon, Jaguar packs, Culchan Skink Cavalry
-Short Bows come back as a skink option
-LM get an artillery piece of some kind
-Javelins and Blowpipes become the same cost and/or Blowpipe skinks get shield options
-We get a new infantry or monstrous infantry type
-Non Chameleon Skinks will get a Scout or Ambusher option.
-LM get their own lore
-Saurus gain a ballistic skill and thrown weapon options
-Saurus gain great weapon options
-Skink Cohorts get spear options
-A unit we have now will be removed from the codex altogether
-The LM 8th ed army book will come out relatively soon.
