From what I know, and I can't cite any of this properly so it could be wrong, there was a lot of speculation in Japan that the Heisei era wold end a few months before when it actually did, more along the lines of mid-2018 than the early-2019 it ended up being. Hence, the Movie Wars for Build being named Heisei Generations Final, as it was intended to be the last Heisei Rider movie. Then that didn't happen and they made Heisei Generations Forever, which is a decent title to go with.

But as for Build getting a higher budget because of this, and supposedly having more 'finality'? I'm doubtful of point A - if they thought the money would get them a decent return, they'd be spending it on every season - and point B just seems wrong? If it means the Heisei Gen Forever movie, then maybe, but that's not even that final for anyone, and Build as a whole doesn't put a bow on the whole era in anywhere near the way Zi-O does. And, of course, you have to consider where Zi-O comes into all this, how early he was planned, especially with the rumours above. That's all for someone who actually knows what they're talking about.
