A centerpiece of the next-generation Apple TV may involve cheap, streaming-only TV rentals, a rumor asserted tonight. Multiple sources understand that Apple would supplement its $2 and $3 episode purchases with 99 cent rentals that would be delivered only through an on-demand stream. As with movies when they reached iTunes, customers would have 30 days to start watching the rental but only 24 hours to finish watching once playback has begun.
