Then again, Britney will have A LOT of exposure the week of her release: YT ads, Spotify ads & Spotify availability, radio deal, lyric video [possibly], audio video, and main iTunes banner. So she might at least snatch #1 on iTunes for a little while, or a few days. Let's all remember that HIAM was released in a week where there was NO competition, so it won't be the same this time around, and she definitely won't be #1 on iTunes for 10+ days like she was then. Know that now.
