Light, torquey engines that are available ate reasonable cost (O.S. will always be a price leader but that does not mean stupid expensive).

They ahve realised that theres a recession going on and that the bread and butter is now in the 30cc and 50cc classes as far as gas engines go.

Anyone likely to buy a ARF suited for 1.20 2Stroke glow to 2.202stroke and equivalent 4 stroke will likely look for a lower operating cost gasser instead.

Bread and butter in the entry level is still a .46Glow or .55 and the new 46AX being based on the 55AX platform seems to bare that out.
