Surface Pro 5 spring release rumors have been picking up steam for quite some time, but new reports offer a somewhat uncertain future for Microsoft’s next-gen tablet. Piggybacking off a ZDNet from Monday, what do we know about the Surface Pro 4 successor?

For those who missed the original story, ZDNet’s Mary Jo Foley has heard from her sources that the so-called Surface Book 2 will not be at Microsoft’s rumored spring hardware launch event. Instead, she puts forth the idea that a new variant of the Surface Book seems possible. In her mind, maybe an entirely new class of device, like a cloud-based notebook, might soon be added to the Surface family.

This thought lines up with the latest round of rumors from Digitimes. The outlet’s supply chain sources have expressed belief that a supposed Surface Pro 2 will use a clamshell design as opposed to convertible. A clamshell would be far more appropriate for a cheap Chromebook alternative like the one Foley has envisioned. 

With that idea in mind, where does that leave the eldest member of the Surface lineup? If there’s no Surface Book 2 release datae planned for spring, is Surface Pro 5 off the table too? In the source report, Foley suggests she is “not sure” if Surface Pro 5 news will arrive soon. This is a topic she touched on briefly during her Windows Weekly podcast with tech insider Paul Thurrott. “I keep hearing no on Surface Book 2, but I haven’t really heard a definitive no on Pro 5,” she mused.

However, the fact that we’re well into spring and have heard very little about the device remains puzzling to say the least. It’s a fact that’s not lost on Thurrott. Later in the podcast, he said "even if they came out with a new Surface that just upgrades the chipsets, that's not enough. That's coasting. These things are due for an overhaul and they need to go to USB-C." The new port “would benefit users tremendously,” he argued. He sees that advantage as something more critical than even a Kaby Lake CPU.

Leaks suggest a Surface Pro 5 device is in development, but its release prospects are unknown at this time.
