Ardent Defender advised #tweetfleet today to cash out their RP, because these RP will be worth much less once Inferno has been deployed on Tranquility:
Of course our friend above is correct, at least partly. Why?
Because if you read the dev-blog about Factional Warfare overhaul carefully, you would have known which datacores to cash out BEFORE Inferno, and which are better to be left until AFTER Inferno.
All Science fields in EVE used to have a multiplier on them until now, which means how fast the RP are generated by the R&D agents, and how much RP Datacores cost. The fields with multiplier of 3x would stockpile three times as fast as fields with multiplier of one, but one Datacore from the 3x field would cost 3*50 RP (150), while the 1x field Datacore would only cost 50 RP.
Once Inferno will be deployed however, all Datacores will have a flat price of 100 RP + 10k ISK. This means that science fields with 1x and 2x multiplier are better to be cashed out before Inferno, but 150RP ones are better to be cashed out after the patch (you will get 50% more datacores at a small 10k ISK fee apiece, which is still much less than half the price of most Datacores).
CCP has promised in the Inferno patch notes, that they will not touch the amount of RP you already have in any way, so this is really the best approach.
I have shamelessly stolen the table from the dev blog mentioned above, but have highlighted which Datacores to cash out ASAP, and what to leave until after Inferno (orange: buckle up and go to your agent now! green: hold until tomorrow)
