There is no way of knowing! As it appears she will be arriving alone, you should be readily available on your mobile in case the Immigration Officer needs to contact you. She might be asked a few questions about you, where she is going to live, etc. when we came in together last year, my husband was asked nothing at all! Maybe someone whose spouse has recently arrived can be more helpful on this one!When arriving in the UK on a spouse visa, will my spouse (who's visa was granted several weeks ago) be further question at the airport?
