It basically becomes a T-20 or ODI at that point which is why Test Cricket will continue dying in my opinion. Was never really a fan of tests to be honest which is why I won't miss them.
ODIs are also becoming less relevant and they might die at some point in the future too. Both these formats will probably be completely replaced by T-10 and T-20 formats which would be a great change overall.
I agree. Already test cricket is on it's deathbed and very soon ODI will be facing that fate. That said, I am horrified with the prospect of T10 replacing ODI cricket. IMO, T10 is not cricket. It is more like baseball. I am OK with the T20 format, but definitely not OK with T10. Why can't we ban this god forsaken format for the general wellbeing of cricket? If the ICC want matches to be reduced to 10 overs per side, then they should reduce the number of players from 11 to 6. Imagine this, 11 guys having a total of 10 overs. That is less than one over per player. Definitely not fair.
I am also not a very big fan of test cricket but I really like to see the skill that is needed to play well in test cricket. In the t20 format, skill is hardly needed in my opinion. I want to see that one-day international cricket never dies, that is the most basic format of cricket. But it does look like what happened to test cricket is going to happen to ODI cricket also and there is nothing anyone will be able to do about it. But I really hope it doesn't get shorter than t20. Because then we will see 11 batsmen in a team or 11 bowlers.
