Intel has already released a lot of information about Merrifield, but they are well aware of the lesson of Osborne, and that is not to over promote the thing you don't yet sell over the thing you sell today.
"People were expecting this and it's due end of this year? Is Intel trying to create more buzz around its independent announcements instead of the trade shows? Or is there something more to it?"
[Merrifield is due at the end of the year and therefore no one was expecting an announcement at MWC 2013. You would be the last person anyone would go to for solid information on Intel release dates...]
Intel referred to Merrifield at MWC and I would guess that introductoin will come early enough to allow products to be introduced, built and make it to the shelves for the holiday season.
