I'm sorry but you are worrying about nothing. World's 11 title 🃏updates were split into 5 before Iceborne and 6 after. I believe Rise only had 2 but Sunbreak had 5 plus a final bonus update. This is what Capcom mean by several.

Capcom's formula for Monster Hunter has long been support (via "several" title updates) for ~1 year, the release of a 💮G/Master-rank expansion, then ~1 year of support for the expansion. After that they'll announce the next game which will almost certainly be a "side" game made for the Switch 2.
