Im Sorry but Until Spelunker don't appear at the PSN Store there's no possibility the Space will come
you're point makes logical sense.
But, a week before the IREM beach came to NA Home I was suggesting to have patience cause the beach space might come to NA Home in time, and some forumers were slamming down that idea and saying "I HAVE PROOF IREM HAS NO INTEREST IN NA HOME. " So and so heard that so and so had heard that so and so had called/emailed/talked to IREM and heard they have no interest.....
but a few days later, I was in NA Home in the Irem Beach lounge.
Now that IREM is in North America, I'd be very surprised if we didn't get everything available here that is currently available in Japan. We many not get it day and date but we'll get it. I suspect that IREM will and is seeing dollar signs galore with their beach wear and cothing line. There is more money to be made in North America than in Japan and most corporations know how to pursue the money trail.
The caves will arrive soon enough.
