Tesla has set a date for its "next" big announcement.  June 20th.

And to make sure they have lots of support, they have sent out some email invitations to some worthy recipients to attend.  The email itself is fairly insignificant, but the lead picture (above) has a curious file name:

So, is this an inadvertent slip foreshadowing a battery swapping announcement for the Tesla Model S?   Or just some more cunning PR work by the California electric auto-maker?
