I am almost sure that COVID must have hampered their plans for a new game because that's the case for many other Game Developers.. Maybe That's why they gave Cricket 19 a DLC.
And the thing Cricket 19 still suffers is the Bugs and the Gameplay issues the game has. I feel like all those things could be resolved in these times to make it much MUCH better. Many other patches and DLC's like BBL and IPL (If Possible coz it's not that easy to get) could be added too.
But still, I would love to see a new cricket game with new features, animations, actions, modes, improved gameplay, more variety etc.., But In my opinion, I think rushing the game out during these times JUST because the new Ashes Series is upcoming is not a good idea. I would want to give them all the time they need to truly make it a Next-Gen Cricket Game.
