What an exciting time for pinball.
Will we look back in 20 years and refer to this time period as the second (third) golden age? Albeit, prices of both new and used machines are up (depending on how you calculate for inflation), but the number of different titles and total number of machines produced across all manufacturers has steadily been increasing for close to a decade now.
While this particular theme doesn't strike a chord with me in particular, I'm sure it will be a HUGE hit, and further the overall growth and introduction of the game to a new generation.
Hopefully, as previous posters have said, this growth will "unbolt" some machines from the floors of collectors who swore they would never sell to chase the next best thing, and hopefully at reasonable prices so that they actually sell.
Me, I'll stick with 1987 to 2007 games until I can consciously justify anything newer. As I would guess, a significant portion of folks in my age range (30-50), love mid to late system 11's (and by extension, D/E / SEGA/ STERN Whitestar), through WPC, to Whitestar. They are my favorite games to play and work on.
