Personally, I don't much care for the tone of this "article." They had the chance to interview Mr. Yoshida and this is all they wrote about it.

Still, as far as those wondering what specs they'll need to play 2.0, this is an interesting anecdote:


Some slightly concerning news for PS Vita. We sat down with Final Fantasy XIV's producer and director Naoki Yoshida at Gamescom, who told us his game's engine is very scaleable so it can be dialed back to fit lower-spec hardware, which is why it works on PC and PS3. We immediately thought of the other logical low-end platform - PS Vita - and asked how feasible that would be as a platform for an MMO like FFXIV. Here's what he told us:

Naoki Yoshida (via translator): "Technically it'll probably work – you could scale it down and get it running. The problem is that in an MMO one of the most important things is the network and so, you know, if you're in a party with a lot of different people in a raid and someone's on the Vita and they have a very... you know, it's not a stable network connection then you're going to be a nuisance to your party members. So global internet networks need to be better. And then also, just more people need to buy the Vita."
The part of this "article" that annoys me is it seems like they're attacking Yoshida for having stated the obvious about the Vita rather than highlighting the fact that this new engine is that scalable.
