Deleted that software off my laptop soon after I installed league of legends. Noticed some immediate improvements in lag shortly thereafter.
As for a June launch date, it would give consumers very little notice. We're mid-way through March. If they announce the console in April and launch in June it gives them 2 months to get the word out there and start the advertising rolling. I don't see it happening, but it could give them an edge and help them steal some of Sony's thunder.
