I agree.
ICM have their Ju88A-5, and two versions of the A-4, plus the A-11 and A-14, so apart from perhaps different decals, I'd guess that the Revell example is identical - pity they didn't 'mix and match' ICM kit parts and release the A-1 version instead. (although it's possible that ICM might release this at some point, using their A-5 as the basis.).
It's likely that Revell and ICM are working in some kind of partnership, possibly with cost / tool sharing, but more likely Revell committing to purchase 'x' amount of kits, allowing ICM to invest in tooling and marketing of their own kits, bolstered by the sales to Revell.
Can't really see an advantage for buyers, at least in the UK - the full retail price of the ICM versions is £27.99, whilst the Revell example is £29.99. (quite a difference to the Canadian price, which is roughly £20.00).
But then, the Revell brand is likely to be more common to the average buyer, especially in high street stores, as opposed to dedicated or specialist model shops, and on-line model outlets. Incidentally, Hannant's do show this kit as 'ex ICM'.
