In 30 years time we'll still have all 3 formats. If we can't even kick out the pointless Champions Trophy then clearly the 50 over World Cup is going nowhere.
I agree :
Tests : only financially viable for a few teams, still an elite select few play it and some not much at all - the big guns won't play more than one-off or 2 Tests against a lot of sides, certainly not the format to 'aspire to' as fans of it might make you think
ODIs : much more globally accessible, and as a comparison of prize money for T20i World Cup and this one will show there is plenty of money in this format, although some of that may have been based on India as hosts ($500k for just being at the Champions Trophy in 2025)
Few sides will become Test sides, if they do it will all end in tiers and no money push cricketers to the more lucrative competitions, so this for many sides is their Test....
T20is : wham, bam, thank you mam, draws the attention of those without much span, too short to be that tactical, and 'evens it up', Is bound to be popular as well as accessible given the duration fits into a much shorter timeframe than ODIs (day) and Tests (up to five)
Purists will cling to the Test format, it has some attraction sometimes but maybe more because it lasts a bit longer and when on top you can really go to town even though in result terms it still only counts 1.... If they weren't so keen for them to last the full $ days where possible they might make it more of a CONTEST, the whole point, between bat and ball. Low scoring Tests for me are the ultimate in that format, many go simplistic and say it just makes it too easy for bowlers but actually if you bowl well you get rewards, bowl badly and you don't, and batsmen have to either dabble and take a chance for quick runs knowing there's a ball with their name on it, or try and grind it out but certainly bowlers have to put it in the right spot or a bad ball is still a bad ball, and late cameos can be deadly
400+ plays 300+ plays 350 plays out to an inevitable win bowling last is pretty dull, too formulaic with not enough variation even though some get over excited by a passage of play or a session or two as if it swings the game
