Considering we're 13 episodes into the 3rd arc and have gotten 2UB focused episodes so far, going by that rate another 13+ for 3 the three UB from the arc poster would put us at episode 88. then the remaining UB's from the OP would give us another possible 13 episodes inbetween putting us at episode 100 by the time all UB's are done, not including Nebby and Necrozoma.
If we take the middle route of Lillie and the firsts arc a the 3rd arc should be 25-30ish episodes long. If that's the case it'd give the 4th and presumably last arc 30 episodes ish to wrap up. If Mallows scene here was actually telling us when the series was planned to end at episode 138 this arc should be ending at the end of august and the final arc beginning in September/October.
It's safe to say we're over the halfway point of Sun and Moon now 74 episodes in.
