It looks like 2 Stroke bikes are confirmed along with the Unreal4 Engine for weather and time of day.
"Milestone surprised us all recently by announcing MXGP 3 earlier than we expected. The screenshots dazzled us with their crisp textures, particle effects and deformable ground, (thanks to the use of the Unreal Engine 4) which was then followed by the official announcement trailer giving us a look at some gameplay.
Milestone has today released their second trailer for the motocross title which confirms the release date of
May 12 across the PlayStation 4, Xbox One and PC platforms.
The trailer (seen below) showcases the existence of two-stroke bikes which will appease many fans that were desperate to have them included. Indeed the trailer itself centres around the inclusion of the 2 stroke bikes with 10 included in total which will have their own physics and of course sound, check out the 2 stroke trailer below. - See more at: http://www.teamvvv.com/en/news/comm...nounced-2-strokes-coming#sthash.JVG40cgZ.dpuf
