Not long after the Lumia 900 surfaced, Nokia's Windows Phone roadmap appeared to have come screeching to a halt -- official and otherwise. However, the first signs of Nokia's second wave may have just surfaced in WP Bench's testing leaderboards. The Nokia Alpha, Phi, PurePhi and PureLambda have all shown up at varying points in the chart; we've seen them for ourselves, although you'll need WP Bench on a Windows Phone to see them first-hand. Not much is visible without seeing the devices themselves, but the PureLambda appears to be running a build of OS 8.0 -- better known to most as Apollo, or possibly Windows Phone 8. As long as these aren't elaborate pranks, they could represent entry, mid-tier and high-end phones; we're wondering if the Pure tag isn't a reference to the PureView-equipped Lumias Nokia said were inevitable in the long run. No matter what the four phones turn out to be, any real devices will show us what Nokia can do with Microsoft's OS now that it's had time to strategize.
