Does Lenovo have an upcoming event to show off new models?

I'm currently in the market to buy a new haswell PC/hybrid this summer, before school starts up again. I'm not interested in the vaio pro after reading multiple reviews, and I'm definitely getting a windows 8 touch screen machine. I know samsung is holding an event on the 20th, likely to show off a series 9 sucessor, but what about lenovo? I haven't heard anything from them... I'm not interested in the helix, and the x1 carbon touch could use more than just a haswell face lift (1080p screen, better price tag... etc). I'm a big fan of the yoga, but I was hoping for something new, not just a refreshed version of it. Is it possible that they aren't releasing anything new and just sticking a haswell processor in the old?

And on another note, when will Acer's S7 be available? Haswell was released 2 weeks ago, and it seems like the vaio pro and mac lines are the only ones with it right now. Maybe I'm impatient...
