I found this info about Rolex at Basel:
Datejust II
We can expect to see more dial options and a dome or smooth bezel option down the road.
Submariner Part III
Basel 2010 is a year when Rolex will complete its upgrade of its popular Submariner. The new stainless steel Rolex Submariner will be out this year, completing the upgrading of the entire line-up of Submariner which started in 2008 with the all gold versions, and ithe two-tone versions receiving an upgrade in 2009. The new Submariner won't be a surprise to many, as it will simply be a stainless steel version of the gold and bi-metal ceramic bezeled Submariner's available at your local Rolex Authorized Distributor today.
Rolex Explorer I and II
Some say that the 36mm Explorer one will be upgraded to 40mm, because alot of dress watches are 36-38mm today.
The Explorer II is to be uppgraded to 43mm for the same reason... bigger is better these days?? Or is it?
Daytona
There was also a rumor of a new 42mm Daytone.
But as 2012 is the 50th years of the Cosmograph Daytona, they will probably wait with that.
And I "highjack" this post for some other news...
Here´s some more news that will be showing on Basel:
