HTC HD7 is my guess that Telecom will start selling soon as both Telstra and AT&T have announced that this is the model they are getting very shortly. Telstra currently sells the HTC Mozart and AT&T currently sell Samsung Focus, HTC Surround 7 and LG Optimus7.
Either XT will get HD7 (higher probavility), Focus, Mozart or Surround 7 very soon.
edit - I hope Telecom retail does not offers the LG Optimus 7Q with the physical keyboard. We have had 2 of these on trial at our work and the hardware is very disappointing. Back gets HOT due to the metal back cover and IMO QWERTY models phones are too heavy.
