All About Microsoft reports that a leaked Dell roadmap making the rounds that shows a timeline indicating that Dell is going to ship a Windows 8 tablet, codenamed Peju, in the first quarter of 2012.

My first reaction on seeing this is… No way. How can this possibly be, given that we haven’t even seen a first tech preview of Windows 8 — and are unlikely to see one, according to most informed (and uninformed) speculation until fall 2011? I’m still thinking Windows 8 will be released to manufacturing in time to make it onto PCs for holiday 2012, but there are also some claiming it won’t be out until some time in early 2013.

  A Windows 8 tablet in Q1 2012? Hmmm...
