May be true, some ppl got it earlier, because they work at a VG store, or know someone who works there. IMO, start with Chimchar or Piplup, NEVER WITH TURTWIG. Since always, grass starters are the most likely to get raped. To start with the others is because Chimchar evolves to Infernape, which is a lot like Blaziken. Or you can take Piplup, which evolves to Empoleon, a Water/Steel type, which being Steel is good, but remember to set up the correct moves.
