Got it yesterday. Level 6 now.
Tons of people in my town have it already. Thought I'd got a very strong Raticate and took it to the gyms. Saw a couple of 800CP Hypno's just chillin' around, and there's one on every gym (though not the same teams, interestingly). Transpires my town centre is absolutely teeming with Drowzee.
Also, Team Instinct. Zapdos is by far the best legendary bird and if the three get released Zapdos will have a very obvious edge in battle against the other two what with being SE against both and resisting flying attacks.
