While I am getting Froakie and Bulbasaur, Bulbasaur's getting boxed right away. I always play through a new gen, the first time at least, with all new Pokemon, and I've decided not to count Mega Evolutions as such (since I mainly do this to help learn names and movesets).
Choosing Froakie (unless chespin is the surprise I'm hoping for or Fennekin and Froakie aren't what I expect), boxing the first gen starter. I love Blastoise but couldn't have 2 waters. I'm still not keen on Charizard's typing and I already want the new fire lioness thing. Never thought Venusaur quite lived up to its earlier forms and the Mega doesn't look any better (ability is fun though)
