Analyzing World Cup Qualifier Changes

The user is asking for an analysis of the FIFA World Cup Asia qualifying schedule changes. I need to clarify which cycle they mean, likely the 2026 qualifiers due to new formats and expansion. Also, I should consider past adjustments related to COVID for the 2022 cycle. The term '赛程变化分析' emphasizes that they’re looking for detailed info on these changes, especially with the progression of Round 1 through 5 and the link to the AFC Asian Cup.Explaining AFC 2026 Qualifiers Format
The AFC 2026 qualifiers format includes 8.5 slots for Asia (8 direct plus 1 for an inter-confederation playoff). In Round 1, the lowest-ranked 22 teams will play in home-and-away matches, with winners moving on to Round 2 and the Asian Cup qualifiers. Round 2 features 9 groups of 4 teams in a double round-robin format, where the top two from each group advance. Then, Round 3 splits 18 teams into 3 groups; I think those top teams qualify for the World Cup, while others move to Round 4, which I’m considering may involve single round-robin matches at neutral venues.Clarifying AFC 2026 Qualifiers Structure
I believe Round 4 is a single round-robin at neutral venues, where the winners from the two groups qualify for the World Cup, while the runners-up move to Round 5. In Round 5, those two runners-up will play home-and-away matches to decide who represents Asia in the inter-confederation playoff. The schedule includes Round 2 starting from Nov 2023 to June 2024, and I need to analyze changes from the previous World Cup cycles, especially how the increased slots and new formats affect matchdays for the top teams.Reviewing Round 3 Changes for 2026
For the 2026 qualifiers, there are three groups of six teams in Round 3, leading to more matches compared to the previous cycle. Each team reaching Round 3 will still play 10 matches, but with more teams overall (18 instead of 12), it means more matches spread across 2024-2025. Additionally, the qualifiers started earlier, with Round 1 beginning in October 2023, unlike the 2022 cycle, which launched in 2019 and faced compressions and centralization due to COVID. Plus, the top two from Round 2 will qualify for the Asian Cup 2027.
