Ah okay, so you're referring to POWER8 with SPEs then. I wasn't sure if you actually meant this or rather the rumoured new Cell in the PS4, which I suspect would be another thing than the POWER8 and presumably in-order again. But specifics on the PS4's CPU are all just rumours yet anyway whereas we definitely know that POWER8 is in the works and that it will probably sport SPE technology. Like you I think POWER8 will likely feature out-of-order execution but I couldn't find any definite information on this so far.
