I sent an inquiry over Digital Anarchy to ask them when they would be selling a OFX version of Samurai Sharpen which is a great video tool and this is what they said
"I'm sorry to say that we will not be releasing Samurai Sharpen for Vegas 15 at this time. We simply don't have enough interest in it yet. We're aware Vegas has been bought by a new company and that they're trying to gain market share in the NLE arena, so we're keeping an eye on it.
If we ever release software specifically for Vegas, Magix will let you know.,they've already been in contact with us. It's just isn't financially feasible yet."
They are not the only company who seem not to want to develop tools for Vegas anymore, I don't think that Red Giant has put out an official update for PluralEyes yet.
We really need these tools unless Magix plans on creating themselves, wouldn't be less expensive for them to pay these developers to port the plugins over than to try to create them themselves?
