Ah! The double-edged sword of a product being bought out and not touched by the new owners. On one side, the product works great and does everything wonderfully, on the other you'll never see any new features added to it. You also won't see their "re-envisioning" of the product either, which is usually a plus!
It takes about 2 months for Reader to go through Repack and Testing before it gets deployed. There's a ton of apps we test interop against, and it takes a while to get all the application owners to test their apps against Reader before it can go out to production.
