No game "SVR 08 Wii" exists. Likely you mean:

Weapon count not officially documented; ~20-30 interactive objects (chairs, tables, ladders, belts, kendo sticks, trash cans, sledgehammers, guitars, mic stands, ring steps, announce table parts) usable in Hardcore matches / Backstage Brawl.
WWE SmackDown vs. Raw 2009 – Added "Create-a-Finisher," more weapons.

SvR 2008 Wii Weapon Notes
