In game, as of writing, today is Tuesday, 11 September, 3049. The clan invasion is upon us, though the Inner Sphere is mostly unaware.
I figured I would post an abbreviated timeline. Much of this is taken from Sarna.net and the 3052 Era Report.
27 September 3048 - ComStar Explorer Corps ship Outbound Light arrives at Huntress. Clan Smoke Jaguar captures it.
21 November 3048 - The Clans vote in favor of invading the Inner Sphere. Clan Wolf is alone in voting against.
August - September 3049 - Clan forces invade the periphery taking 22 Planets in their pre-invasion wave.
13 August 3049 - Phelan Kell captured by Clan Wolf at The Rock.
2 Novemeber 3049 - ComStar makes contact with invading Clan forces.
January 3050 - Precenctor Martial Anastasius Focht is appointed the ComStar Ambassador to the Clans. He meets them and opens negotiations.
7 March 3050 - The first wave of Operation Revival is commenced. By the end of April the Federated Commonwealth, Free Rasalhaugh Republic, and Draconis Combine will have lost 35 planets.
May 3050 - The Second Wave commences.
So for those of you who are saying. "It's still two years away." You need to remember, we've been on these forums for a year or so. By this point the Clans have already taken the Bandit Kingdoms including the Oberon Confederation. Phelan Kell has been taken bondsman.
The periphery is dark. A communications breakdown is the assumed cause. We have 6 months left until the first wave of Operation Revival begins. So conceivably, some of us could be meeting Mad Cats on the field at any time the devs want. (Does Paul ride a Summoner?) The rest of us will see them in 6 months. As for when the players will have access to them, your guess is as good as mine. Just keep in mind, the invasion is not as far off as you may think.
PS: If people find this post useful, I will update and fill out the timeline.
