How amped is Microsoft to get developers into the Windows Phone 8 Store? The company announced today at Build that it's lowering developer registration to $8 -- that's down from $99. Got to get in there quick, however -- that price is only good for the next eight days. Seems to be some kind of theme here, no?

Update: Looks like the discount situation is a little more involved than just that. According to Microsoft, "You'll be charged $99 USD or equivalent in your local currency, and we'll refund the difference in the next 30 to 45 days." Ninety-two percent discounts don't just happen overnight, after all.
