https://youtu.be/aQ_qtyOa5Dg?t=17m24sIshihara says "Pocket Monsters series no honpen". Honpen means "main entry" etc, the translator translates this as "main series Pokemon RPG".
https://www.youtube.com/watch?v=aQ_qtyOa5Dg&feature=youtu.be&t=17m14sIshihara says "Pocket Monsters series no saishinsaku". Saishinsaku means "latest entry", the translator translates this as "the newest titles in the mainline series of Pokemon RPGs".
From this, it seems like they're treating "mainline Pokemon series" as "those games that are called Pocket Monsters in Japan" (as opposed to all those random spinoffs, which tend to just have "Pokemon" in their title), but Ishihara isn't actually standing there saying there are "core Pocket Monsters games", "non-core Pocket Monsters games" AND "Pokemon games".
