Any early Pacific campaign is going to present interesting challenges, to both sides. F4Fs, P-39s and P-40s in the Solomons against A6Ms, and trying to intercept IJN bombers that are coming in, in your slower climbing Allied planes, or P40s and 39s in New Guinea going up against the slow but agile Ki-43, then out of nowhere running in to a sleek, fast and still agile Ki-61 that can stay with you in the dive.
Much to look forward to.
