Plenty for us SQ guys, and the bassheads can have the class D gazillion watt amps. I know not having a dedicated class A/B sub amp or two channel A/B amp that can be bridged for a sub, but I think Morgan already addressed this.
I do indeed use the rear channels of my Ti500.4 for my subs. If I were to hypotetically look for a new amp, it would be a 2ch A/B to power the sub at 4 ohms bridged, so I could add some midbasses to the front stage off the rear channels of the 500.4. 2ch amps may not sell as much, but I still think they are an important option to have, since you cannot totally replicate their usefulness with 4 channels and monoblocks. I figure they will probably come out later if there's enough demand for them, for now we are definitely getting the most important amps.
Since the smallest new Ti sub amp is going to be 1500w, which I think is an absolutely pointless amount of power for any SQ purposes (though I may consider running one at a higher impedance), this forces me to use the smaller R-series class D monoblocks for sub power. I just don't see myself installing a run of the mill class D monoblock though. I also have a subjective bias against 1 ohm optimized amplifiers, since towing the PG line over the years trained me to think it is important for amplifiers to make power at higher impedances. Everyone and their dog has kilowatt 1 ohm amps, but only PG made amps that would play over a kilowatt at 4 ohms (T1500.1, X1200.1, ZPA0.5). I always thought low impedance optimization was a sign of "cheap" amps. But clearly when we had our brainstorming sessions, I was one of very few who weren't asking for multi kilowatt amps and subs, so I am definitely not the majority opinion.
I am curious to see what the size of the new Ti 4 channel amps is going to be. I am limited in space with what I can install under my parcel shelf... the Ti500.4 or maybe an X100.4 is about as big as I could fit. Then again without fan cooling I am not sure the new amps would be able to be mounted upside down anyways, which would be a dealbreaker in my case.
This is all speculation at this point so I guess we'll just have to wait and see. I will hold out for internal pics of the Ti 4ch amps. Also very curious to see the new components and subs. Since the RSD series was so excellent, I would like to see that taken another step higher in the Ti series.
