HTC knows you’ve seen those leaked renders of the One M9 Plus, but just to remind you it’s coming ahead of Mobile World Congress next month, the company has been teasing the unveiling of “something HUGE” on Twitter.

“Something HUGE is coming from HTC,” the company’s official U.S. account tweeted. “Imagine [number][big thing] in space. And then [math term] that by [number].”

It’s all very cryptic, but of course, that all adds to the excitement. HTC won’t confirm anything before its event on March 1, but rumor has it the One M9 Plus will essentially be a bigger version of the standard One M9, with an additional physical button that’ll have a built-in fingerprint scanner.

HTC’s last flagship “phablet” was the One Max, a larger version of 2013’s One M7, which also had a fingerprint scanner on its back. Last year’s One M8 never got a bigger brother, but some sources claimed there were plans for a One M8 Prime that eventually got scrapped.

If you’re excited for the One M9 Plus, you have less than two weeks to wait for MWC.
