The 9th and 10th entries in the series will include all of the DLC released for those titles. Capcom also released some information on amiibo support for the game on the Switch in an official blog post. That's not a huge surprise given that the original Legacy duo was divided up to make room for Mega Man 1-10 across two games, but there might be a silver lining to all this for Switch owners.
Not only will the collection be bringing 10 Megaman experiences to the hybrid console, it will be sporting some interesting new features along with it. However the company only stated that the games would be released in the Spring of 2018, which was rather vague, but now we have a more concrete release date. You can also rewind gameplay at any point, allowing you to brush up on those tough-as-nails sections that used to cause you headaches as a kid (unless of course you're too young to have played them, in which case, thanks for making us feel old as shit).
Those fan-made challenges were previously exclusive to the Nintendo 3DS Mega Man game; this marks their debut on the Switch. The first collection will cost $15 as a digital download and the second one will be $20. The collections may be purchased as separate digital downloads through the Nintendo eShop or as a package through retailers. While Mega Man Legacy Collection 2 launched previous year for PC, PlayStation 4, and Xbox One and included Mega Man 7 through Mega Man 10. You'll also be able to buy the first collection and a code for the second one (along with a 30th anniversary cleaning cloth - yay?) for $40 in May.
