But if apps are made with cross platform tools, they're not specifically targeting WP7.8 phones, but both WP7.8 and WP8 phones. Since the vast majority of apps don't need the enhancements, I don't see why the developers would make their apps specifically for WP8, i.e. why would they throw away their current know how just because they can? Now, over time, this will likely chance if the Windows 8/Windows phone 8 platform takes off, but that's not in the near future, and as I pointed out, by the time this scenario happens (or not), it would be the time to upgrade your phone anyway..
