First Partner Series 3, released August 7, 2026, completed the originally announced trilogy covering all nine mainline regions' starter Pokemon. That naturally raises the question of whether The Pokemon Company plans a Series 4, and if so, what regions it could possibly cover.
As of this writing, there's no official announcement confirming a fourth series exists or is in development.
Here's an honest look at what's actually known, and what a hypothetical Series 4 would even need to cover.
In the meantime, the existing nine-region trilogy remains a genuinely complete, satisfying collecting project regardless of whether a future series ever actually materializes.
The trilogy structure was consistently framed as covering all nine existing regions, which suggests it was designed as a complete project rather than an open-ended series. Without a new mainline region to draw from, there's no obvious content gap for a Series 4 to fill.
That doesn't rule out a future series entirely — The Pokemon Company has extended other product lines before — but it means a Series 4 isn't a natural, expected continuation the way Series 2 followed Series 1.
The most straightforward path to a genuine Series 4 would be a new mainline Pokemon game introducing a tenth region, giving a fresh trio of starters to build a collection around. Until that happens, there's no clear thematic hook for extending the format.
An alternative path could revisit an existing region with alternate art treatments, though that would be a meaningfully different product than the original trilogy's one-region-per-collection structure.
Whether or not a Series 4 ever happens, completing the existing nine-region trilogy remains a solid collecting goal on its own. EVORETRO's Ultimate Card Curator Set gives the current set real room to grow.

Official Pokemon Company announcements around new mainline game reveals are the most reliable early signal for whether a future First Partner series becomes possible. Dedicated Pokemon TCG news outlets typically report on any product line extension announcements quickly once they happen.
Until there's an official announcement, treat any Series 4 rumor as speculation rather than a confirmed upcoming release.
The Pokemon Company has both extended and retired product lines before based on collector reception and available source material, so there's real precedent either way for how a First Partner-style project might continue. A strong-selling trilogy is a reasonable case for eventual continuation.
Watching how similar product lines have been extended in the past gives at least a rough sense of what conditions might eventually justify a Series 4.
Rather than waiting on an uncertain future announcement, focusing on completing the existing nine-region trilogy is the most productive use of collecting time and budget right now. A confirmed, existing project is always a better use of resources than speculating on an unconfirmed one.
If a Series 4 is eventually announced, collectors who've already completed the original trilogy will simply have a natural next step to look forward to.
Rather than waiting on Series 4 rumors before deciding what to buy, most collectors are better served completing the existing nine-region trilogy first, since that's a confirmed, finite goal rather than a speculative one.
If a Series 4 does eventually get announced, having the first three series fully organized makes incorporating a fourth series into an existing system far easier.
Checking official Pokemon TCG announcement channels periodically remains the most reliable way to catch a genuine Series 4 confirmation early, rather than relying on secondhand rumor threads.
No, there's no official announcement as of this writing.
A new mainline Pokemon game introducing a tenth region would be the most natural path.
The framing suggests yes — all nine existing regions were covered across the three series.
No, there's no confirmed timeline, so completing the existing trilogy remains a reasonable goal now.
Until a Series 4 is officially confirmed, the nine-region trilogy already released is a complete, worthwhile collecting goal on its own. Pick up EVORETRO's Ultimate Card Curator Set to keep building toward it.
