There's a new special edition Wrangler for 2014 - the Rubicon X. It appears to be a 10th anniversary Rubicon without the red leather seats. I like it myself (but the $46,600 price tag is getting up there).
2014 Jeep Wrangler Rubicon X | Jeep JK
What would be nice is if jeep paid attention to the purists and not the johnny-come-lately pink hat wearing yuppies (although that is the main demographic for jeep currently)
Build a stripped down rubicon, no navigation, no auto swaybar do-hickies, no leather or carpet but a absolute stripped down jeep with rubi axles (or better) and 4.1 t-case, heck make it a 4cyl and offer it at a competitive price. They would sell the ba-jeebus out of them to people who would actually use them as intended.
For the cost of this particular vehicle ($40G's+), I can build an older YJ with LSX motor, better axles and gearing, make it safer and plenty more capabile and still have money left over to buy some gum and a 6-pack.
I think that Jeep is doing OK with all of these special editions. They'll make a couple of extra thousand off those that can afford it, and the rest can buy a base model.
As to offering a 4 banger - keep in mind that that most Wranglers sold today are automatics, and Jeep's been burned in the past by mating the 4 banger to an automatic. If you could get Americans to drive stick again then maybe it would be possible.
