Dayummm... Pokemon XY must be way off!
We dont have pre order numbers from Diamond/pearl. Some People here (like 5-10) think it'll sell less than 12mil lifetime O.o
Here is a comparison of HeartGold/SoulSilver pre order numbers (why I think there should be alot more)
Titles HeartGold/SoulSilver X/Y
Final Pre order Numbers (US)⇒ 396,108 390,819
Pre order Numbers With 1 Week Left⇒ 100,833 43,461 (WTF is this BS?)
Pre order Numbers With 2 Weeks Left⇒ 35,492 42,109
Pre order Numbers With 3 Weeks Left⇒ 48,328 29,481
Yeah doesn't add up, Heartgold/soulsilver did do 11.5mil lifetime but still! I think pre orders will be higher than 600k imo
