There's also the myTouch 4G Slide (T-Mobile US) and the Samsung Captivate Glide (AT&T). Both work internationally though neither are sold outside the US (and Canada for the Captivate Glide), AFAIK.
The Desire Z is still sold though it is getting harder to find (e.g. retailers like expansys don't seem to have it any more). On the other hand, T-Mobile also recently had a surprise revival sale (now over, I believe) on its twin (the G2).
There are also a fair number of lower-end QWERTY devices (both Blackberry-style and sliders), but there is absolutely room for a high-end QWERTY "hero". Personally, I'm rooting for an HTC One Z (with a T-Mobile G3 twin?), but we'll see.
SE Xperia Pro, Slide, Captivate Glide, Desire Z? It seems like another problem with the diversity of hardware is coming up with names that don't sound like something you would buy from a vending machine in a truck stop restroom.
