Windows Insider leader Dona Sarkar has posted word that the Windows 10 team has "some really interesting things" planned for the next Insider builds that could launch late this week or next week.
No new builds today #WindowsInsiders tho we're hustling some *really* interesting things for you late this week & next week. Thank you! <3— Dona Sarkar (@donasarkar) June 7, 2016
It's very possible that some of those "really interesting things" could be related to what Microsoft might reveal on Monday, June 13 at E3 2016.
