The only difference I see between Capcom for Vita and 3DS is pretty much the same!
For 3DS, you listed one port. You also listed an original game made from old assets, Mercenaries 3D, which you referred to as a port. You also listed an expansion, MH3G, which you called a port. Then you listed five original games, one of which is going to be part of a multimedia franchise. And you also forget that sound-based original title that Capcom released early in the 3DS' life, something something mansion.
You then listed two ports for Vita. Dragon's Dogma Quest is coming to iOS before hitting Vita, so I'll let you decide if that's multiplatform or not. It's not an exclusive at any rate, and it certainly doesn't suggest that the two systems are being treated the same.
As for "3DS has 3 ports before it started getting original content." I don't think that Capcom needs to hit a certain number of ports before they start releasing original content - we knew about Revelations before the 3DS launched, if I recall.
This week's thread sure is snipey
Console launches in the air.
I always think it's terrible when we start grouping members into camps. It's a lot better when it's the statements that are discussed.
