ing psyched for this game, as I sold my pearl and need to get back into IV, as there was a lot I missed (such as the metagame). I have a few questions though:
1) If someone temporarily trades me the event Regigigas, can I still get the 3 golems?[/quote]
Yes, but you need to have the national dex, which requires beating the meta-game and seeing all 150 Pokemon in the Sinnoh Dex. You then need to have the Regigigas on your game (in your party I believe) to be able to catch the Regitrio.
[quote2) Should I be able to find it at GS w/o preordering easily or do I have to preorder to have the game in my hands this Sunday?[/quote]
Gamestop, possibly. Wal-Mart or other big chain retailers like Best Buy & Target, most definitely.
3) Can I get Ubers through wifi trade (even if not GTS). I think after beating the game I want to get me a shiny new Arceus AKA POKEGOD
Yes, you can pretty get much anything can be obtained through the GTS, or anyone wanting to trade with you. Although, every Arceus you currently find will 100% be hacked, because it has not been officially released yet by Nintendo.
4) Any news on the Arceus special event?
I personally haven't heard anything myself. It will most likely be given away at the release of the 12th Pokemon movie in Japan, since Arceus is the main character.
5) How do you pronounce Arceus?
