Lenovo's PSREF page shows a new Legion Y545 model that is listed as being available in the Western Europe and Russia regions. The Legion Y545 is very much identical to the recently launched Y540 apart from sporting an aluminum construction, button-less trackpad, and RAM options up to 32 GB.

RAM up to 32 GB... like the Y520 which supports 2x16GB DDDR3 but which Lenovo does not document to sell new laptops?
Looks like costco.com is also selling Y545.
