W10 for phones on Surface RT, 2 and Lumia 2520

[hacer619]

W10 for phones have native compatibility with keyboards and mice. This made me think that Microsoft didn't implement this feature to be available for phones only (it's not even practical or even productive), well, maybe keyboards. Also, there's no reason for RT tablets to not be upgradable. If you remember, Windows phone 8 and Windows 8 share the same kernel and so does Windows RT. So, if Windows phone 8.1 is upgradable to W10, RT tablets should be upgradable. Theoretically, its only a mater of updating drivers.Do you think Windows 8 RT tablets will/should be upgraded to W10 for phones?
