I can see 20 new additions from your list with that 1.5.2 update. I would have to see for myself if there are any others.
- Power Surge Optimus Prime (the new large toy that has the Aerobot Minicon)
- Warrior Power Surge Optimus Prime (red)
- Warrior Power Surge Elite Optimus Prime (white)
-
- 1-step Switchblade Night Bumblebee (redeco)
- Power Hero Bumblebee (the new large toy that has the Buzzstrike Minicon)
- Hero (3-step) Power Surge Bumblebee (redeco)
-
- Power Hero Sideswipe (the new large toy that has the Windstrike Minicon)
-
- Hero (3-step) Drift (orange)
-
- Minicon Weapon Windstrike (red)
-
- Warrior Windblade
-
- 1-step Ratchet
- Warrior Ratchet
-
- Warrior Scorponok
-
- Starter Bisk (non-toy game character)
- Legion Bisk
- One-Step Bisk
- Warrior Bisk
- Hero (3 step) Bisk
-
- Warrior Paralon (redeco Scorponok)
- Warrior Scatterspike (redeco Quillfire)

There should also be a couple more Minicons (Aerobot and Buzzstrike), as you had Windstrike (for the Power Hero Sideswipe toy), so the partners for Optimus and Bumblebee could be there as well.

These on your list were already there before this update...
- Desert Optimus
- Pumpkin Optimus
- Legion Ratchet
- Battle Pack Alpine Sideswipe


I just downloaded the update but the game itself didn't update anything after it was finished and re-opened.
Actually... it is doing one new thing - it won't scan the Ultra class Megatronus codes properly anymore (it doesn't unlock the character and give ultra sparks, it just gives you a powerup.

Looks like android got screwed again... or maybe it's just me and my misfit tech.
