Although the arrival of Game Boy and Game Advance to Nintendo Switch was something that glad all fans of the company, the initial selection of games was not as great as we saw it with the NEW, for example.
While we already know that titles such as Fire Emblem and Pokémon TCG will reach these platforms, we do not know when, and it seems that the great n does not know either.
Recently, Stephen Total, axis journalist, asked Nintendo if they planned to add new games to Game Boy and Game Boy Advance applications every month.
Unfortunately, it seems that this is not the case.
This was what the company responded:

There is no established calendar for new releases, but each collection will continue to grow.
Recall that NEW and SNES applications received games every month, but with more than 100 titles between these two platforms, and the arrival of others has spent a lot of time since this pair received an update.
For its part, the N64 received a new installment every two months, while the Sega Genesis obtained a couple of games, but with the same frequency.

Considering that Nintendo still plans to offer support for N64 and Sega Genesis, it is likely that Game Boy and Game Boy Advance do not receive monthly updates.
Even if we have to wait more than desired, it is clear that games like Golden Sun, Fire Emblem, The Legend of Zelda Oracles of Season & Ages, and more, will reach these platforms in the future.

Similarly, this is the complete list of games available for GB and GBA.
Editor’s note:
It will take some time, but I am sure that some of the most iconic games of Game Boy and Game Boy Advance will arrive at the switch.

Only the idea of playing Metro id Fusion is more than enough to keep the monthly or annual payment that many have.
