After a bit of rotation in paint.net the screen on your pictures comes out as equivalent to 1080 by about 1600, so I think the 1080x1620 rumour seems pretty plausible.
Anyone reminded of the old Sony Ericsson P1? Looks quite similar! I'm keen on checking this out. MWC can't come soon enough!
hopefully, they remove that silver band on top and make it one color like the classic BlackBerry look and feel. right now, it is so reminiscent of sony ericsson p1i. i
