Well, the consensus is that Baiken will benefit from metagame changes as other characters are changing, and having a few extra tools like an AA that isn't a baitable and evadable guard cancel - a "DP" will also be nice.
However, we just don't know right now. The game is still in testing and revision, and until that settles itself and until people actually start playing the game, we just won't know the technology or be able to judge. We won't even know what we're dealing with until months after it gets released. It could be Baiken will just be unable to compete because her good matchups just have the tools, now, and her damage isn't consistant. Maybe she'll be S -tier. We don't know.
Baiken isn't one of those "fundamentally basic" characters I keep hearing about and told to pick up by vets. She has her own strengths and we will need to see them in action, and it'll probably take a little while to see what's what in the new version. You can't just say "Good normals that are fast and big with good hitboxes" and call it a day.
My take on it is, "I can't do anything for a while - focus on game fundamentals and techniques for defense."
Unfortunately I don't have the means to effectively practice due to technical problems.
Hope this helps.
