The broken record is at it again.

Where's my screwdriver?

After the PS4 sells like Vita, third parties will be forced to support all because of mediocre sells.

Yes, they have Japan all to themselves. They won't have any of the west for the core games.

Sure. It's like a mid-range vs high-end PC. It could very well get good 3rd party support. In order to get that, however, it needs to get a good install base. If the install base is large enough 3rd parties will bring titles to it.

The man with the crystal ball strikes again. PS4 will sell even less than the Wii U then, its settled. Also, I hope you'll keep that sig long enough to be embarassed about it.

I bet you anything that after a year or two of the same dreary outlook on things and poor numbers, you'll just escape like all the similar members we used to have (people with big mouths and a lack of insight who go around and insult others at every turn while claimig superiority). 2013 and 2014 will be very hard for you.

Meanwhile, they'll be perfect for me, I'm upgrading my PC this fall and really don't give a shit how the consoles do. The PS4 looks like a machine for the twitter/instagram crowd, I'm gonna let them have it to themselves. And I doubt the next xbox will be very different, perhaps more restrictions and fees. And we already know what Nintendo brought to the table (this table is looking worse and worse to me).

I dunno, but some signs are pointing towards good support (Watch Dogs is obviously a great start, though more is needed).

All comes down to infividual devs now. I'm not holding out much hope, however.

I think being the cheapest to develop for and being able to manage most of the engines, I think it will have good support, we haven't had a Nintendo direct with 3rd Parties so we'll have to see!

Nuh uh.  The support graphic Sony showed was mostly Japanese.

As for the OP, I think next gen engines can scale back to the Wii U.  However, it's going to be really important for early third-party games to sell well on the Wii U or that support might dry up quickly.

Realistically speaking, this all depends on Microsoft now. 

If the NexBox is closer in power to the Wii U, Sony will be the one left out in the cold (well not left out, but nobody will take full advantage of the HW). UE4, and other engines are scalable, so there won't be as many NexBox/PS4 games that won't release on the Wii U. 

On the other hand, if the NexBox is close to the PS4 in power, Nintendo may be in a tough place, but it all depends on 3rd parties at that point. 

it depends what nextbox will show us. if it will be as strong as ps4 it ill be hard for wii u to get a much support as ps4 and nextbox, if ps4 will be the only really strong console it could look much different.

€dit: i just should have quoted IAmAwesome who said pretty much the same but yeah, scalable engines are also something we have to consider.
