Intel's deskbook CPU platform merger plan

When exactly does Intel plan to align its desktop and notebook processor families around the same architecture? Recent roadmaps cited by Japanese web site PC Watch put it in 2006 with the launch of 'Merom' and 'Conroe', the mobile and desktop versions of the Pentium M-derived architecture. But DigiTimes today cites Taiwanese notebook-maker sources who claim it will happen with 'Jonah', believed to be the predecessor to Merom, possibly as early as H2 2005.

The sources do note that the transition could take place as late as H1 2006, which would seem to put it back into the Merom/Conroe timeframe. Jonah is expected to ship sometime in 2005 and be fabbed using a 65nm process. The successor to the 90nm Pentium M, 'Dothan', Jonah is believed to have been designed around a pair of Dothan cores each connected to 2MB of shared L2 cache. The question is, does the earliest/latest dates offered by the Taiwanese sources apply to Jonah alone or to Jonah and Merom/Conroe? Or has Intel brought forward its architecture harmonisation programme to the Jonah generation?
