Query: where's the battery

i bought the batman tumbler rc for christmas for my 5 year old son. We still are unable to purchace a batttery for this toy, and today is March 7th. maybe next year i can get him a battery for the 60 dollar car that has been decorating the toy shelf all year. When, I wonder, should i expect to be able to get the battery for this "great toy"?
