The list is updated. TV_Game doesn't release in odd months and past episode doesn't have any new debut. However, magically Floette has been marked as "standard" and there are spoilers tags behind.
Also, for people interested, those are the older pokemon debuted (if the user can't update in 26 days the new pokemon,I don't recommend doing the older species) if we ignore BW.
In that cae, Helioptile and Goigoat debut in XY1. Noivern will dot he same in XY5. The rest are:
XY001: Pikachu, Meowth, Wobbuffet, Rhyhorn, Jigglypuff, Doduo, Lickitung, Ditto, Medicham, Swanna, Ampharos, Azumarill, Swablu, Chatot, Furret, Hoppip, Furret, Bidoof, Bibarel, Magnemite, Watchog, Vulpix, Smeargle, Stoutland, Flaaffy, Delcatty, Panpour, Skiploom, Pichu, Raichu, Mareep, Aipom, Surskit, Poliwhirl, Politoed, Sentret, Pidgey, Weedle, Caterpie, Burmy, Wormadam, Zigzagoon, Tediursa, Sharpedo, Luvdisc, Wailord, Magikarp, Seaking, Horsea Seadra, Lanturn, Lapras, Tentacool, Tentacruel, Marill, Oddish.
