Both are wrong, is Pokemon Platinum.

for that "strong seller", you may be right. Platinum releases this Friday for us europeans, and i for one am going to camp outside Gamestation (fuck you GAME) and i know a few other people who are planning to first day purchase the game also. I was just wondering whether they'd announce US/EU dates for Mystery Dungeon Sky at E3.

well they also have proffessor layton and spirit tracks for the 2nd half, those are some pretty big titles. and i think we will get DSi exclusive carts as E3 too

DSi only carts are something to be shown at the E3.
Pokemon Platinum will be releasing this friday, so it's pretty hard for Nintendo to point on Heart Gold/Silver Soul for this summer. And the same goes for Pokemon Mistery Dungeon. Maybe Professor Layton 2? They need a boost for DSi sales.

That may be, but the fact still remains that Gamestation always have better deals for me. I get nothing but awesome deals at GS: Fresh copies of Madworld and Sonic Black Knight for £17.49 (will probably pick up Madworld), Ninja Gaiden II for £9.99 fresh, just awesome deals all around basically.
GAME on the other hand still sell preowned copies of Red Steel for £30, RED STEEL!! What are you doing!! Gamestation still have a section for GC titles, and the odd rare GC game that i want may just pop up. GAME gave up on GC, even when we were in that era, GAME never had anything i wanted. Not to mention GAME lack the almighty glass cabinet that houses the retro gems. no, sorry but Gamestation > GAME
