There is really no evidence to suggest that any "complex advanced features" are what are causing the delays with the new pre-pro.

It is entirely possible that there are rather mundane production issues related to things that have nothing to do with how simple / complex the product is and might be resolved very quickly. (Please lets hope it is not another contract manufacture getting pressured by a fearful mainline brand...)

Personally I think it is admirable that the leadership of Outlaw Audio does as much as they can to bring high quality products to market at a very attractive price; the trend for too many brick & mortar AV dealers is to move increasingly toward prices that do much to kill off all but the wealthiest buyers.

I look forward to news of the availability of their latest product and given the relative stabilization of video standards and audio the lifespan of these products could very well fit with the admirably long lived amplifiers that they've built their reputation upon. It makes a good argument to consider a higher end pre-pro as being something that will provide years of service...
