Hi there,
I'm from Japan who is anxious about the rotation rumored soon to be announced in Japan. I'm just a newbie at PTCG and not even familiar with English pokemon names, though.
I've checked the timing for each expansion of DP, Pt, and HS sold in the US.
I noticed that "9 packs to start the season and ends with 13" is not correct. "10 packs to start and ends with 14" is right. It's four packs a year and makes 2.5 to 3.5-year card pool.
DP4 2008-02-01 Great Encounters
======== the border
DP5 2008-05-01 Majestic Dawn
DP6 2008-08-01 Legends Awakened
DP7 2008-11-01 Stormfront
Pt1 2009-02-11 Platinum
Pt2 2009-05-16 Rising Rivals
Pt3 2009-08-19 Supreme Victors
Pt4 2009-11-04 Arceus
HS1 2010-02-10 Heart Gold & Soul Silver
HS2 2010-05-12 Unleashed
HS3 2010-08-18 Undaunted

What about the 2011-2012 rotation? Pt1 to be dropped???
Talking about Japan, Pt-on makes 2.5-year card pool for the next season starting January 2011. Besides our Pt is not your Pt, how can we make a battle at the WCS??
