The same guy mentioned several days ago, again on Twitter, that all applications developed for WM 6.5 would be incompatible with Windows Mobile 7. On the other hand, Greg Sullivan, Senior marketing manager of Microsoft has already stated the next generation operating system will be able to run in two screen resolutions only. Assuming the information of Mr. Murtazin is correct and the fact that the famous HTC HD2 will get an update to WM7, the second native resolution supported by the platform will probably be higher than 480x800 pixels. Did anyone mention HD? Well, this is still just a rumor, but fingers crossed (we would keep even our toes crossed if that could help) that Microsoft finally reveals the whole truth about Windows Mobile 7 at MWC 2010 that is to take place in the middle of February, 2010.
