Most equipment manufacturers today usually market their iron sets 5-PW or GW, assuming most players want hybrids or 5 and even 7 woods replacing the long irons.
If not for all sets, the L100 iron set (which nearly identical in spec to the L97s except for meter) would be a great place to offer a mix and match or hybrid set, and give the veteran and heavy players an incentive to buy new gear, likely at a premium price, and really make it an endgame set with superior attributes.
Nah, they'll just make another $15 ball that goes poof when it's used up.
