Gameinformer is a side effect of having the power-up rewards card.
Also most of the multi-plat previews are well after I have seen them online so you can't say they didn't know about Wii versions all of the time. If they are trying to be a "professional" game magazine maybe they should know something that's been on sites like gamespot, IGN or even Gamestop.com months before the issue comes out (listed and avail for pre-order most times). They have a "consoles" section for a reason, to "inform" customers of which console(s) it's coming out for.
it's just alot of the times they are a bit favourable and wish they would just step up and admit it. Last time anyone said anything to them about it (and it wasn't a whiny or immature letter) they jumped all over the guy like a bunch of arrogant jerks. They take after what seems to be the atmosphere at alot of GameStops most of the time. Uninformed yet act like they "know-it-all". Most of the time it's like they don't work for a game store but a sony or microsoft store. Sure it's ok to have an interested in one particular console but the purpose of the store is to sell ALL inventory not just a select part.
