The PA announcer at Ho Ho Kam, Tim Sheridan, has his own blog where he gives various updates on the Cubs, Mesa, and the ballpark.
Recently, he posted some further information on the changes coming this March, which include:
... improved Cubs merchandise stores, 2 new auxiliary scoreboards installed over the 1st and 3rd base patio areas so you can see a scoreboard from any location in the stadium. And a brand new state of art main scoreboard said to cost over $500,000 which is more than the entire price tag of building old Hohokam Park in 1977.
If all of this, plus the previous info I posted a few weeks ago, comes to pass, Ho Ho Kam Park could become the best park in the Cactus League.
