Pokémon Dream Radar is scheduled to release on October 7th (the same day as Pokémon Black 2/White 2) on the 3DS eShop, followed by the PokéDex 3D Pro on November 8th, but until now, Nintendo has remained mum on the subject of pricing.
Another game allowed you to catch Pokemon in the real world too.
Invizimals actually did this before Pokemon in 2009
"Unlike Pokémon however, Invizimals requires the player to hunt and capture these creatures within the real world, using the concept of augmented reality"
"Having previously used photography as a basis for a spin-off, Pokémon Dream Radar is holistically in the same conceptual ballpark as fan-favourite, Pokémon Snap, this time using augmented reality as its main mechanism. The difference here is, Snap had an all-encompassing vision, while this...this just reeks of being a tremendous afterthought. Regardless of whether you're a fan of the franchise or are looking for a generally good AR game, it doesn't make a lick of sense how Pokémon Dream Radar could be viewed as anything but a bare cash-in." -- Wiiloveit.com

As the free Pokédex 3D application retires from the Nintendo eShop, Nintendo dutifully deliver a replacement in the form of the Pokédex 3D Pro.
Whereas the original saw users receiving three Pokémon a day through SpotPass, all content is available from the get go with its successor. Yet, at such a stomach lurching price point, is Pokédex 3D Pro worthy of your cash?
The dream radar at $3 isnt bad I guess,but the PokeDex at $15 is another story
