I don't think we've heard anything to date about crossplay. Historically, Ubisoft titles have not had crossplay (Siege, For Honor, etc.). However, there seems to be a growing movement among the industry to start moving / making more advances in that direction. Since S&B is still pretty nebulous right now, it's not inconceivable that its final incarnation might end up offering crossplay opportunities, but I wouldn't get my hopes up.
unlikely. Not until Xbox 5 or PS Scarlet release. It is why i think ubisoft delayed the game. But even if they did- consoles players would get *** f.cked by pcs. Running at 30 vs 120+ fps is a major game changer.
Add to it the ability to play at 140 hz while consoles locked to 90hz. You create a secenerio were PC players win 100%. Since gaming mice have a response time of 0.010 ms. Vs the 50 ms on a controller. It would be like mike tyson fighting a 3 year old baby
