A dubious leak claims that the HTC 11 will have 6GB of RAM and 128GB of storage. While the specs could be spot on, the leak appears to be a fake. The IMEI number doesn't correspond to HTC devices and the UI in the image appears to be from a Huawei phone.
According to @LlabTooFeR, the new HTC U Ultra will not be HTC's 2017 flagship device. Instead, the unannounced HTC Ocean is presumed to be the HTC 11 and will be unveiled later this year. Meanwhile, the HTC Ocean Master has been canceled.
It's been reported that HTC will be replacing its One series flagship smartphones with the new HTC U series. However, CNET is now saying that someone "familiar with HTC's plans" denies this claim and the One series will live on.
