"A more linear, classic experience"
I would have preferred if you improved on the old Metroidvania play style. This linearity implies nothing. It could just maintain the linear speed of the original, as Sonic's running was pretty much automatic.
"We have a new character, Amy Rose"
This has confused many, but Amy was not playable in Shattered Crystal, like how Sticks wasn't in Rise of Lyric.
"The people who hated Boom contributed to bad sales"
Many people were more or less indifferent to Boom. The games also recieved bad reviews because they were terrible. RoL in particular was a complete failure.
"We no longer consider the Wii U version canon."
R.I.P. Perci. Also, this does show that they were aware Rise of Lyric was a flop. They aren't aware it tainted Boom by being the figurehead.
Overall, Pee and Poo will be another faliure and continue the state of crisis at hand.
