NiN sure seems to think so. Everything you read about Switch says NiN isn't waiting and is pushing hard to get the Switch out asap. Not before proper software is ready though of course.
I can totally see PS thinking about coming out with a PS4Portable. PS right now is pushing out hardware like madmen, and its all linked to the PS4, so a portable that plays down scaled PS4 games definitely could work.
PS likes to compete on all fronts, so Switch being a new type of hardware, will no doubt be tempting for PS to try and emulate, especially if the concept takes off.

PS2 - @- We must build a console that offers online living room gaming.
PS3 - #- We must build a console that’s powerful, social, costs and does everything.
PS4 - $- We must build a console that’s affordable, charges for services, and pumps out exclusives.
PRO -%-We must build a console that's VR ready, checkerboard upscales, and sells but a fraction of the money printer.
PS5 - ^ -We must build a console that’s a generational cross product, with RT lighting, and price hiking.
PRO -&- We must build a console that Super Res upscales and continues the cost increases.
