The correct usage is "wait for you".
Google has a tool to see which usage is more common; while this doesn't always tell you what is right, it often helps. For these terms, "wait you" starts out at one-fifth as common as "wait for you" in 1800, but by 2000 it's 3% as common. "Wait to you" is pretty much zero throughout. I think that this is because "wait" used to be used where we now use "await"; now, if you want to omit the "for", you have to say "I await** you."
Looking through the first few results for "I wait you", the first one is "For you I wait", so that's still "I wait for you", but with different word order. The second one is "I wait, you little ones". So there, "I wait" is a complete clause, and "you" is part of a noun phrase. The third is "I wait. You shout". Again, "wait" and "you" aren't part of the same clause. So it looks like recent uses of "I wait you" are not in fact using "you" as a direct object of "wait".
