Speaking to AutoExpress, Andy Pfeiffenberger said the area of the brand's range below the RX will see some development "over the next few years."
While that's a pretty vague statement, it doesn't take much reading between the lines to see a sub-RX model as its focus. The question as to what it might look like is answered largely by the competition.
A handful of variants are likely, including four-cylinder (though not likely turbocharged), hybrid, and possibly even plug-in hybrid, given parent company Toyota's ongoing development in that field.
While the "next few years" is equally vague, we wouldn't expect to see a production sub-RX crossover on the show stand, much less the roads, before 2015, possibly as late as 2017.
