I agree on some points and disagree on others, it's ultimately a matter of the point of view. Let's leave it at that, this is not the right place to discuss it. I just hope Valve knows what they're doing, I really don't want them to get into trouble due to this.
It will be interesting, it's been a very long time since anyone has notably entered the game market.
Wii U will be fine in either case, but I don't know if the hardcore numbers that they want will come Nintendo's way, if steam box launches this year. hopefully that can bring this all into context, because that's the only real reason I was discussing it here.
I also don't think steam will enter the market in a hostile way, I believe they will still port their titles to the other consoles, and I think they will stay 3rd party in any case. At least I really hope so... Would love to see HL3 for Wii U launch.
