John is on loan at Portman Rd until the end of the year but from his comments he would quite happy to leave Palace.
He told the Ipswich Evening Star: "The chance to come to Ipswich was out of the blue but it didn't take me long to decide to come here.
"I have to take one step at a time, and see what happens in January, but for sure I'd like to stay longer.
"My contract at Crystal Palace ends next summer, though with a possible one-year extension depending on appearances. But I'm a million miles away from that.
"The club has financial problems, and it's in a tricky situation."
