I would say 'yes', more or less.
The EX uses sensors in which the valve stems are part of the sensor assembly. As long as the new rims can accommodate this style of TPMS sensors, there shouldn't be much of a problem. TPMS has been mandatory on new passenger cars sold in the US since 2008. So if you're getting a brand new set of aftermarket rims, I would think that most, if not all, of the wheel manufacturers have made their wheels TPMS compatible. If you really want to be sure, check with the manufacturer of the wheels that you plan to buy.
And if you're upgrading to another set of late model Infiniti rims, then it shouldn't be a problem at all.
When getting the TPMS installed, the only thing I've heard that you might want to do is to get a "rebuild kit" since the sensors are already disassembled from the wheel. It's not mandatory, but this is one of those things you do for peace of mind.
