there are many different theories to the whole two season deal. see when it was first announced, they said there would only be 20 new episodes. then they have confirmed that there will be 40+ new episodes. so whether PRS is having two halves, like previous series is possible. also there is a rumour that the first 20 would be 2011 and the last 20 would be 2012. all speculation at the moment. then there was an announcement that the PRS banner would last for 2 years. much like MMPR lasted for 3 years, just with different themes. whether they adapt goseiger under the PRS banner remains to be seen.
and before anyone says how can angels and cards come under samurai, jus remember a tyranosaurous themed ranger controlled both a dragon and a gorilla. anything is possible with the right creative direction.
also, the 35th sentai ties in with the 20th PR. rumour currently states that the 35th sentai will be a sequel of sorts to goseiger, and carry on the card theme, as well as keeping datas. i cant see PR messing about with their 20th anniversary by not adapting goseiger
They are going to show over 40 episodes and it will be on Nickelodeon, one other thing, Thanksgiving Day, there are suppose to be something on Power Rangers, then after the parade, Nickelodeon is going to start showing promos of that new series.
