The surprise announcement of the Quickdraw throws the doors open to unexpected announcements for the IS mechs released this year.

Ground rules:

• Unseen aren't happening. It's a foregone conclusion that if they were possible, they would be added to the game as quickly as possible. There's really nothing to say about that other than complaining about it not happening or wishful thinking. Go whine about it on the official forums or something.
• Quad Battlemechs and LAMs are out. Since they're all Unseen at this point, it's not a big deal.
• Nothing introduced after 3052. Again, you can whine about the timeline, but this much isn't changing given how many time-appropriate options there are.
• Current tech only. This is all IS mechs, and anything that would need a special exception to the current real-world or in-game technology (speeds over 150, MASC, a LAA on one arm, splitting weapons between components) is possible but much less likely.
• I've skipped all of the TRO 3058 and 3075 mechs that are described as extinct in 3050, like the Lynx, Talon, Hammerhands, and Helepolis. There's a bunch of them, they're all goofy-looking, and nobody much likes them. It's possible that PGI could put them into MWO, but very unlikely.

Those limitations in mind, what mechs might we see?
