A keyspace of 1024 bits is double that of 1023 bits. Prime numbers become more scarce as they go on. For instance, there are two primes in a keyspace of two bits. In a seven-bit keyspace--which, by your logic, there should be thirty-two times as many primes--there are only twelve and a half times as many. Primes are spaced out further and further as numbers grow larger and larger. In this case, Arjen Lenstra is closing in on RSA-1024 with great alacrity. Lenstra is a reputable cryptographer, and his results are quite interesting.
