Just saw the post on Autoblog this morning.

350 out of a twin turbo four is great if you ask me, and we know their reason behind it is mainly to increase efficiency without turning the car into a glorified K-car. Ford's squeezing 30mpg out of their 300hp V6 in the Mustang (on paper), so getting equal if not better numbers both in power and fuel economy in the Boxster compared to its outgoing engine is quite alright with me. Even the Corvette has a rumor flying about that it'll end up with a 3.X OHC (finally) V-8 putting out similar if not better power than the current high displacement engines they run.
My one thing about this change is that I'm curious to see how it will sound (praying they won't go for that ugly Subaru burble). I took a co-worker for a spin in the Boxster and he turns to me and says: "...it doesn't sound like a Boxer engine." to which I pretty much said "No, see,
this is how a Boxer is
supposed to sound, not that Subie burble that you like." He changed his tune a bit after he heard the car really wind up.
And I really doubt it's going to have any lag issues, but we'll have to see if it runs out of breath on the high end. Porsche may be making their upcoming 911 look more like a Panamera than the other way around, but I really doubt they're going to do something that'll totally piss off their clients.
