There's a lot of context involved with this announcement, so let me break it down:
In Japan, the three games are set to launch on May 23 for Nintendo Switch eShop and at Japanese retail. They will be avaialble individually and as a triple-pack.
The first game is also available for PlayStation 5 as Neptunia reVerse. This version launched in December 2020 for Japan and June 2021 worldwide. Neptunia reVerse can be considered as an enhanced re-release of a re-release of a remake of the original Hyperdimension Neptunia on the PlayStation 3.
Re;Birth 2 and Re;Birth 3 are also planned for PlayStation 4 release in Japan, but no release date or pricing has been stated.
According to a statement given by Idea Factory International (the western publishing branch) given to Gematsu, there are no plans to release the PlayStation 4 versions of the three Re;Birth games in English.
All that being said, a Japanese announcement trailer and western game descriptions can be found below, via Idea Factory.
We are excited to announce that Hyperdimension Neptunia Re;Birth 1, Hyperdimension Neptunia Re;Birth 2 Sisters Generation, and Hyperdimension Neptunia Re;Birth3 V Generation are arriving digitally (North America and Europe) for the Nintendo Switch in 2024. For the first time since the original release on the PlayStation Vita, the Neptunia essentials can now be played on-the-go. The Nintendo eShop pages will be available at a later date.
Hyperdimension Neptunia Re;Birth 1
In the world of Gamindustri, four CPUs (also known as Goddesses) battled for supremacy in the War of the Guardians. One of the CPUs – Neptune – was defeated by the others and banished from the heavens. In her fall from grace, Neptune’s memories were lost, but a mysterious book revealed itself to her with knowledge of all of Gaminudstri’s history. Joined by Compa, IF, and the sentient book known as Histoire, Neptune embarks on an extraordinary journey across four different nations on a quest to save the entire world!
Hyperdimension Neptunia Re;Birth 1 Key Features
Now on-the-go! – Previously only available on PSVita and Steam in North America, now you can immerse yourself in the zany JRPG madness of the Hyperdimension Neptunia Re;Birth series for the first time on Nintendo Switch!
Revisit Classic Neptunia RPG Style Battles – Battle with up to 3 characters on the field, with 3 more as support. Use them to perform special attacks or swap them out at any time!
Switch it Up with Plans – Use "Plans" to customize the game by changing up enemy difficulty, dungeon treasures, and more!

International Crime - morality has all but vanished. As much as 80 percent of all students are rumored to worship a being known as Arfoire, and the authorities have chosen to turn a blind eye to the threat. Basically, Gamindustri is pretty messed up, you guys. Ahem. Thus did Gamindustri fall into complete and utter disarray.
Will the Goddesses be able to reclaim their world from ASIC’s grasp, or will they be forced to wander the Gamindustri Graveyard, forever lost?

Hyperdimension Neptunia: Re;Birth 3 V Generation
It’s time to Nep-Nep like it’s 1989. Neptune’s been sucked into an alternate dimension of Gamindustri! In order for her to escape from this late ‘80s world, Neptune will have to collect enough shares to open up the path to her own dimension. Sounds easy enough – except a nefarious alliance called the Seven Sages wants to rid Gamindustri of all CPUs (also known as Goddesses), including Neptune!
Forging cross-dimensional friendships, will Neptune be able to defeat the Seven Sages, save this alternate dimension and get back to her own, or will she be stuck in the ‘80s forever?
