According to a report over at Bloomberg, HTC apparently ditched its plans for a large-screen Windows Phone 8 device.
It appears that despite earlier leaked roadmap that showed a "Zenith" flagship smartphone with 4.7-inch Super LCD 2 display and quad-core Qualcomm CPU, it appears that we will not see it anytime soon. Apparently, HTC does not want to do a large screen WP8 as it will end up with a lower resolution when compared to the competition.
The current HTC WP8 flagship, the HTC 8X features a 4.3-inch Super LCD 2 screen with 1280x720 screen which is a long way from the 1080p screen on HTC's Droid DNA/Butterfly Android flagship. Nokia Lumia 920 has a few pixels more and a bit more screen real estate with a 4.5-inch 1280x768.
Looks like WP8 will be still stuck with compact and mid-range screens, at least if you ask HTC.
