So how about a little 'Dex discussion?
In the past, GF has included the pokemon they planned to give out as events in the regional pokedex. I could be wrong, but that was the main reason for including Manaphy in DP, both Mew and Celebi in HGSS, B2W2's Genesect, etc. With them already having plans to release an event Torchic, I think it's reasonable that they'd include it in the regional dex for Kalos, and that would mean that Treecko and Mudkip are somehow available as well. I could be way off here, but it's plausible.
