For power, you need high PSI at high rpm so a big turbo. For fast and available torque low down, you need a small turbo. Also high PSI needs lower compression ratio, but this kills engine efficiency, so variable compression systems have to become a standard feature. This is expensive technology. But it will probably come the next two years. Wen it doesn't, there will be no combustion engines left and everything will get Teslafied.
More cyl and higher displacement is only ok, when you don't want to invest in technology. But it will be wiped out soon anyway: way too many pump, friction and inertia loses. I6 and V8 is nostalgia.
Future is small or not at all.
