The tweets are from a writer at BLOOMBERG, not an MS employee.
MS has since come back with a statement saying the news is basically false,

"Here’s what you should know – ALL consumer electronics products have a lifespan, and the Zune HD is 18mo old. We were completely frank about this year’s Zune hardware being the WP7 phones, and we continue to both sell and fully support the Zune HD line of products. And as I’ve promised – we continue to bring new apps and games to the platform. More of those are in the works, I promise you.
I manage business development for Zune hardware, and I still have that job. Our PR folks released a statement today that included the text: “We’ll share more information about the evolution of the Zune entertainment service and Zune hardware as future plans develop.”
To be 100% clear – NO information about our future plans, no matter what the incarnation, has been shared. Until then treat with healthy skepticism anything you read. That’s probably a good general rule actually.
So for those who tweeted or emailed asking what I’m “going to do now” – I’ll be going to work tomorrow, working on Zune hardware bizdev. And when Microsoft announces news that is actually news, you’ll hear it from us directly, and I’ll be sure to pass it on immediately. Only then should you take it as gospel."
