This is incorrect news although being reported in some credible sites. Firstly, CI hasn't mentioned anything and neither has wikipedia's page on the event. I hardly believe cricket europe would report a story before CI.
Secondly, this is a dangerous game for the host country to have to qualify. NZ, WI aren't far ahead of BD in ODIs - in fact, NZ was behind till very recently. If the same thing happens in T20s they may find themselves fighting over scraps with the Associates. They'd rather keep BD and ZIM in the top 10, than risk themselves being demoted along with the Associates.
I drop knowledge so heavy it leaves the world unbalanced, exterminating the spiritual force of all that challenge, I'm the lyrical apocalypse that crumbles the granite, replacing you as the dominant species on the planet.
