I would love to see Buck make a knife the size of the 112, with a mid back lock, much lighter weight, solid G10 scales with no liners, large pivot, using CTS-XHP or S90V steel. Tall order? No, I think this is right down Buck's alley. I want a drop point blade, but a clip point is also good.
Why no liners?
I had a Bucklite Max 482 for a bit...

It developed horrible amounts of vertical blade play in about a year's time. In an email exchange with the folks at Buck, I was told that linerless knives (of that time - the Bucklite Max and the Bantam) just aren't as durable as ones with liners (at that time, the Ecolite and 110/112 and 500 series). I'm not 100% convinced though as my Ecolite 112 developed significant amounts of vertical play in about the same amount of time.
I'm not sure that liners => weight, if weight is the issue. My experience this summer carrying a large Case Sodbuster has demonstrated that to me in spades. It has liners, a very robust pivot and, by virtue of no bolsters and light, derlin? scales, very light. It's almost the same size as a 110 but infinitely easier to carry in my front pocket.
The Buck that sees the most pocket time for me is the 500 Duke. Mine is an older one with Micarta scales.

It's not a light knife but I've found that thin frame compensates for weight. That is, I can tolerate a heavy thin knife better than a light fat knife. The 500 carried much, much better in my pocket than my Ecolite 112 did - this despite the fact that the Ecolite was so much lighter.
Lastly, I personally don't want to see different frame styles in terms of their profiles. I think the 110, 112 and 500 frames are perfect in their side profiles just the way they are. I just want the 110 and 112 to be thinner (as in Sodbuster thin) and lighter (as in Sodbuster light) and with more durable pivots.
To my mind, this means bolsterless design (like the Bucklite Max and Ecolite series), thinner frames (like the Bucklite and 500 series) and burlier pivots (like <no carrier>
