aren't the PSN cards printed in real currency amounts?
I'd imagine MS doing the same with their cards.
and I hope they convert whatever existing points you have in your account ( and on all current point cards ) into the equivalent dollar amount.
it would really suck if you lose all of your current MS points, or if that $20 1600 MS point card you just bought ( but haven't redeemed yet ) doesn't work after the conversion.
oh, and they just started their "Rewards" program not too long ago. will they reward you in real currency now?
