True, but even Scizor rarely carries a bug move outside of Volt-Turn cores. (In which case it's generally U-Turn.)
Someone over on the Smogon discussion thread brought up a good point:
The Eeveelutions match up to their pre-gen-4 type colors, for the most part. Leafeon is more beige, but is still in the green color group and covered in leaves. The red and blue on the ribbons look a lot like the red and blue of the Dragon icon. Dragon is also the only pre-gen-4 Special type left to make an Eeveelution for. Also, if you look at the CoroCoro page, the name Ninfia (ニンフィア) is written in giant font in the exact color scheme of that icon.
That's not a bad point, I'd just think that it would look more ... dragon-y at first glance.
A tiny group of people say dragon because they're willing to completely ignore the pokemon's appearance and name because of their desire for pattern completion.
That is a downside to the theory, that it doesn't look very draconic. Well, a lot of the dragons don't. Behold!
Dragon seems to be a type that they slap onto a Pokemon to make it special. That makes sense, because Dragon is arguably the best type in the game, rivaling Steel. There is only one more special type to do, and they'd have to do a dragon eeveelution anyway if they were doing all the types. Most new eeveelutions show up in pairs. This one is alone, which makes it different. It would be very difficult to make Eevee look draconic, but this one does look remarkably different from the others in shape. I'm not saying it's guaranteed to be dragon type, but you can't really deny that it's a significant possibility. At least in the same order of likeliness as normal or flying.
As for the name, it's hard to say what Ninfia is supposed to represent. Eifie is the Japanese name of Espeon. At first glance, it doesn't look like much, but is apparently a pretty easy portmanteau of
esupaa (esper) and
fiiru (feel). Umbreon is called Blacky, and Flareon is called Booster. Until we get an English name, it's basically impossible to call.
