My initial predictions...
1. Regional variants: Tentacool line (based on Portuguese Man'o'War), Swinub line (based on the Wild Boar... maybe switch to Ground/Grass?), Seel line (based on the Monkseal), Poochyena line (based on Iberian Wolf, possibly with a third stage), Roselia line (based on flamenco dancing - a Grass/Fire type would be awesome for this...).
2. New pokemon in existing lines: Tauros/Miltank pre-evolution, Cherubi alternate evolution (themed off grapes rather than cherries), Sunkern alternate evolution (blood orange theme), and Kecleon evolution (chameleons are native to southern iberia, among other places).
3. Pokemon returning that weren't in Sw/Sh: Oricorio, Furfrou, Skiddo line, Scatterbug line, Deerling line.
