WP7, new minimum requirements

[gTen]

Microsoft's latest WP7 chassis spec includes second-gen Snapdragon, optional gyroscope -- Engadget

So it looks like WP7 upped the minimum specs..and suprisingly allowed an 800mhz phone in even though 1ghz was suppose to be minimum (even though its obvious the 2nd gen snapdragon even at 800mhz is superior)

----

So now we can continue the discussion on before..as it seems M$ chose the route of frequently updating the minimums..which boils down the question...what happens to all the people that bought a 1st gen snapdragon devices? are they gonna continue to get updates or be left out? (and if so for how long)
