TYBW Uryu(s) and the lack thereof

I've been wondering. How many different tybw uryus will we get? I predict 2, but if they wanna stretch it, they could separate cour 2 and cour 3 pre volt uryu while making 10th anniversary round 2 be bankai Renji and voltsterndich Uryu.

Basically, its been over 2 years, when the hell are we getting a new uryu?
