The first time I played it through when it first came out I got up to that rock boss in phendrana drifts - maybe a bit further. I've restarted it though, and am not that far - I've had a bit of a busy week.
I'm currently playing... well... I suppose I should be playing my DS games... but WarioWare has taken over. Polarium and Pokemon Dash got played once on Friday evening and moved over for WarioWare and various website updates.
