According to a report by The Verge, it looks like those of you who have just purchased a Nokia Lumia 900, an HTC Titan II or any other new Windows Phone, may be a little upset when Microsoft drops the newest version of Window Phone, 8 or code named Apollo.
A trusted source, close to Microsoft, when speaking with The Verge, contradicted a recent report that said all current Windows Phone devices will be upgraded to Windows Phone 8, that’s simply not the case. ZDNet’s Mary Jo Foley, said that while they [Microsoft] can confirm that all existing apps in the Marketplace will run on the next version of Windows Phone, they have nothing to say about future updates.
This isn’t really that surprising, when factor in what the next version of Windows Phone OS will offer. With the addition of multi-core processors, higher resolution displays and screen sizes, it sounds like “Apollo” could be a drastic change, at least under the hood, which could prevent older devices from running as smoothly as they do now.
Of course, this is all speculation as of right now, so until we hear it from the horse’s [Microsoft's] mouth, take it as just that.
