Tom Warren over at The Verge , who has been fairly reliable in the past, believes Microsoft is hinting at a 2560 x 1440 Surface Pro and high density 7-inch tablets at the BUILD conference going on this week.
“…Microsoft appears to be dropping some accidental hints at the future of Surface and other 7- and 8-inch tablets.” -Tom Warren
One session at Build talked about building apps across multiple screen sizes, during the session Microsoft showed potential screen sizes for Windows 8 tablets. One of these resolutions was a 10.6″-inch tablet running at 2560 x 1440. This may potentially be the next screen resolution for the Surface 2, which is currently 1920 x 1080. There also lies the possibility this will be a tablet by an OEM or unannounced ODM design that has not been publicly announced yet.
Other potential display resolutions shown included a 7-inch display running at 1920 x 1200 and a 7.5-inch display with a 1440 x 1080 resolution. OEMs may be shipping these high resolution 7″ – 8″ tablets in the near future. Interestingly, these numbers show for the possibility of a 4:3 and 16:10 aspect ratios for these tablets.
One potential issue with these higher resolutions is a negative impact on battery life, but with Haswell this may be less of a concern. Another issue is that with higher resolution and touchscreens you typically have DPI enabled; Windows supports up to 500% scaling, but most users will typically not deal with anything past 200%. With the scaling you lose some of the potential workable space than without scaling. However, user demand for high density displays is greater than ever.
