"Timeline of Generation IV Releases"

#PokemonGO: In honor of today being the 6 month anniversary of the initial release of Generation IV, I've put together a brief timeline showing which Gen IV Pokemon have been released, when they were released, and which ones are yet to be released. Legendary and Mythical Pokemon are denoted by italics. I pulled the dates mostly from old TSR posts, but I've been known to make mistakes (from time to time), so let me know if you see any errors. I've also excluded releases from other generations (Clamperl, Gorebyss, Huntail and Smeargle), but they did occur within the timeframe I'm looking at.​For a TLDR, since the January 31 wave, we've only seen Happiny, Mamoswine, Dialga and Giratina-O released from Gen IV.​October 16, 2018Turtwig, Grotle, TorterraChimchar, Monferno, InfernapePiplup, Prinplup, EmpoleonStarly, Staravia, StararaptorBidoof, BibarelKricketot, KricketuneBuneary, LopunnyShinx, Luxio, LuxrayRiolu, LucarioChatotCarnivinePachirisu​October 23, 2018Drifloon, DrifblimStunky, SkuntankSpiritombGiratina (Altered)​November 6, 2018BudewBuizel, Floatzel​November 14, 2018RhyperiorMagmortarElectivireMismagiusGliscorPorygon-ZHonchkrowWeavileRoseradeTogekissDusknoir​November 20, 2018Cresselia​December 18, 2018Bronzor, BronzongSkorupi, DrapionCroagunk, ToxicroakFinneon, LumineonSnover, AbomasnowChinglingMunchlaxMantykeHeatran​January 29, 2019Palkia​January 31, 2019AmbipomLickilickyTangrowthYanmegaGalladeFroslassCranidos, RampardosShieldon, BastiodonCombee, VespiquenGlameow, PuruglyBonsly​February 16, 2019Happiny​February 16, 2019Mamoswine​March 2, 2019Dialga​April 2, 2019Giratina (Origin)​Not Yet ReleasedBurmy, Wormadan, MothimCherubi, CherrimShellos, GastrodonMime JrGible, Gabite, GarchompHippopotas, HippowdonMagnezoneLeafeon, GlaceonProbopassRotomUxieMespritAzelfRegigigasPhione, ManaphyDarkraiArceusShaymin (Sky), Shaymin (Land)​Edits - added Shaymin, fixed Happiny's release via /r/TheSilphRoad http://bit.ly/2Gf5TEG
